    @MikeThomsen Thanks for merging this. Although my original intent was keeping commits made by @trixpan separated (not squashed) to retain his credits, it looks good to me because the original PR 4196 and 4175 are closed as I expected. @trixpan Thanks again for originating this improvements!

    @ottobackwards I assume you were talking about this, #2016. That one adds user/password for proxy authentication at abstract AWS processor. This PR adds ProxyConfigurationService, which can be added on top of #2016 for AWS processors proxy configurations to be managed by the centralized Controller Service. Please look at the FTP and HTTP processors in this PR, AWS ones can adopt the CS same way.

    @jugi92 FTPTransfer supports SOCKS proxy. Specifically at these lines:
    ```
             if (proxyType == Proxy.Type.HTTP) {
    -            client = new FTPHTTPClient(proxyHost, proxyPort, ctx.getProperty(HTTP_PROXY_USERNAME).getValue(), ctx.getProperty(HTTP_PROXY_PASSWORD).getValue());
    +            client = new FTPHTTPClient(proxyHost, proxyPort, proxyConfig.getProxyUserName(), proxyConfig.getProxyUserPassword());
             } else {
                 client = new FTPClient();
                 if (proxyType == Proxy.Type.SOCKS) {
                     client.setSocketFactory(new SocksProxySocketFactory(new Proxy(proxyType, new InetSocketAddress(proxyHost, proxyPort))));
                 }
             }
    ```
    https://github.com/apache/nifi/pull/2704/files#diff-6e7e715d42f332cbe404edd9afbcaafaL533
    
    For processors those don't support SOCKS proxy, following validation code should be added into their customValidate method, to confirm that ProxyConfigurationService is configured with the supported proxy type(s):
    ```
    ProxyConfiguration.validateProxyType(validationContext, results, Proxy.Type.HTTP);
    ```
    
    ProxyConfigurationService just holds the centralized proxy settings, each processor is responsible to use the settings with its own relying SDK/API way.
    
    I checked #2018 but the PR doesn't look active. I will take a closer look on SFTP processor and #2018 to see if I can include SFTP ones into this PR, too.

    @ijokarumawak haven't had a chance to take a look at this, but have you tried it against Solr and Elastic yet? I think the latter's APIs do their own proxy management so that might need a little finessing here.

    It would be very nice if the initial proxy service also includes a SOCKS Proxy example. Other processors that implement the Proxy Service can then reuse the existing implementation even better. For example we would probably implement that change for the SFTP processors then.

    I found a bug in this in the aws implementation, I am not sure how you would see it in the other processors, I found it when bringing this code into my Gateway Api PR.
    
    The issue is that customValidate validates that both host and port need to be set, but not that both user and password need to be set.
    
    Since I test for this ( from the InvokeHttp testProxy ), I fail.

    How will this work with the AWS components?  They have proxy as well ( although there is a PR for full support ), but a different builder I think

    @MikeThomsen We can combine ProxyConfigurationService into ES or Solr, the CS just let users manage proxy settings in a centralized place. I will take a look on #2094 to see how I can help review that one. Thanks.

    @jvwing Good catch, thanks. I removed the duplicated PROXY_HOST and PROXY_HOST_PORT. The missing one was LIST_TYPE. So, 17 + 3 = 20. 3 additions are PROXY_USER, PROXY_PASS and LIST_TYPE.

    Added 3 more commits.
    
    1. Added proxy support to Azure processors.
    2. Adding more explicit Proxy spec check and doc. Due to the restrictions of underlying libraries, Proxy support spec varies. Based on the investigation summarized in this PR's description, I've used 4 labels to represent spec HTTP, HTTP_AUTH, SOCKS and SOCKS_AUTH.
    3. Incorporated review comments.
    
    Example screenshots:
    InvokeHTTP does not support SOCKS_AUTH, so if ProxyConfigurationService is configured with SOCKS and username/password, then it becomes invalid, but SOCKS without auth can be used:
    ![image](https://user-images.githubusercontent.com/1107620/40225356-c5e6a30c-5ac3-11e8-8bb4-9541144e6491.png)
    
    PostHTTP does not support SOCKS at all:

    Not only validation, property description shows what proxy is supported:

    SFTP processors are the only ones supporting all Proxy specs:

    https://github.com/apache/nifi/pull/2704
  
    @ottobackwards You are talking about these code specifically?
    ```
    HTTPUtils.setProxy(context, clientBuilder, credentialsProvider);
    ```
    
    Then yes, the above util method accepts HttpClientBuilder and useful for processors those only use HttpClient library. It's currently used from only GetHTTP and PostHTTP. It's just a convenient method for those two for now.
    
    Other processors who don't use HttpClient, uses ProxyConfiguration directly to get proxy settings. Following snippet is copied from AbstractAWSProcessor:
    
    ```
    // Get Proxy configuration from ProxyConfigurationService if it's used, or from processor's own proxy configurations, either way, the configurations are put into the `proxyConfig` instance. And subsequent code do not have to care how where these settings are set.
    final ProxyConfiguration proxyConfig = ProxyConfiguration.getConfiguration(context, () -> {
        if (context.getProperty(PROXY_HOST).isSet()) {
            final ProxyConfiguration componentProxyConfig = new ProxyConfiguration();
            String proxyHost = context.getProperty(PROXY_HOST).evaluateAttributeExpressions().getValue();
            Integer proxyPort = context.getProperty(PROXY_HOST_PORT).evaluateAttributeExpressions().asInteger();
            String proxyUsername = context.getProperty(PROXY_USERNAME).evaluateAttributeExpressions().getValue();
            String proxyPassword = context.getProperty(PROXY_PASSWORD).evaluateAttributeExpressions().getValue();
            componentProxyConfig.setProxyType(Proxy.Type.HTTP);
            componentProxyConfig.setProxyServerHost(proxyHost);
            componentProxyConfig.setProxyServerPort(proxyPort);
            componentProxyConfig.setProxyUserName(proxyUsername);
            componentProxyConfig.setProxyUserPassword(proxyPassword);
            return componentProxyConfig;
        }
        return ProxyConfiguration.DIRECT_CONFIGURATION;
    });
    
    // Apply Proxy settings to underlying SDK/API.
    if (Proxy.Type.HTTP.equals(proxyConfig.getProxyType())) {
        config.setProxyHost(proxyConfig.getProxyServerHost());
        config.setProxyPort(proxyConfig.getProxyServerPort());
    
        if (proxyConfig.hasCredential()) {
            config.setProxyUsername(proxyConfig.getProxyUserName());
            config.setProxyPassword(proxyConfig.getProxyUserPassword());
        }
    }
    ```
    
    Does that answer to your question?

    - ListS3
    - FetchS3Object
    - DeleteS3Object

    Minor tweak: The check for PROXY_HOST and PROXY_HOST_PORT duplicates checks above on lines 309-310.  I believe this is why we add 5 lines of new assertions, but the count of property descriptors only goes up by 3 from 17 to 20.  It doesn't make any difference, really, but the math was bothering me.

    @jugi92 Thanks! I actually didn't know SOCKS protocol supports user authentication.. It seems SFTP processors (thanks to the underlying jsch) support that. I've added your suggestion and confirmed with Dante SOCKS server with authentication.

    I will update this PR shortly.

    Elasticsearch processors are also included in this PR now.
    I'm researching on AWS and Azure processors now, but those can be done separately.

    @ijokarumawak I'm going to start reviewing this. Once we get this done, I could use a hand with a review on [this](https://github.com/apache/nifi/pull/2723) lookup service I wrote which I'm partly holding back so I can do its proxy support via your changes here.

    Now this PR includes SFTP processors and SOCKS proxy support for SFTP as well.

    I recommend a separate `name` vs `displayName` for PROXY_USERNAME.
