METRON-1875: Expose configurable global settings in the Alerts UI
## Contributor Comments
This PR exposes a JSON file that can be used to configure the Alerts UI. Properties in this file are read on startup and available through an `AppConfigService` that can be injected. The use case in this PR is a configurable REST API path. This path was hardcoded throughout the Alerts UI code but can now be changed in the configuration file directly. A restart or rebuild is not necessary, the change is visible as soon as the Alerts UI is refreshed in the browser. I think this could be generally useful for other use cases in the future.
### Changes Included
- An `AppConfigService` was added that loads configuration settings by requesting the config file as a static asset.
- The various services were updated to use the `apiRoot` configuration setting instead of a hardcoded url.
- We currently load column names from local storage on startup. I don't believe this is used anymore so I switched the initialization call to `AppConfigService` and removed the unused code in `ColumnNameService`.
- Updated the unit tests to inject a mock `AppConfigService` instance.
### Testing
To test this feature, spin up full dev and verify that the UI continues to function normally. Edit the file at `/usr/metron/0.6.1/web/alerts-ui/assets/app-config.json' and set the `apiRoot` property to a different value. Refresh the Alerts UI and verify the api path reflects the change in `app-config.json`. For example if I changed `app-config.json` to be:
```
{
"apiRoot": "/some/api/path"
}
```
I would expect to see the search request url (in the network tab of Chrome developer tools for example) to be `http://node1:4201/some/api/path/search/search`.
