> Implement a new PostSlack processor which is able to upload and attach the FlowFile content (eg. an image) to the Slack message.
> The current PutSlack processor uses Slack Webhooks which have some limitations:
> - file uploading not supported, only text messages (which can contain attachment links, but not the file to be uploaded itself)
> - the current version of Slack Webhooks do not support the runtime configuration of Channel, Username, etc, parameters any more, so these properties of PutSlack have no effect
> To overcome these limitations, the Slack Web API needs to be used instead of Webhooks. Due to this technology change, it is better to reimplement the functionality in a new processor than extending the existing one.
