## What changes were proposed in this pull request? [KNOX-3198](https://issues.apache.org/jira/browse/KNOX-3198) - Check for async supported on SSE requests This is a QoL change for HA and non-HA SSE requests. For every SSE request it checks that async support is turned on. The SSEDispatch is created during the first request so there is no way to give a faster error response to the user. Now it doesn't fill the logs with stacktraces only logs a single error line and gives a proper error response on the request. ## How was this patch tested? - Unit tests, manual tests - HA and non-HA SSE requests with async support turned on and off `curl -iku admin:admin-password https://localhost:8443/gateway/sandbox2/sservice/sse/3` ``` <html> <head> <meta http-equiv="Content-Type" content="text/html;charset=ISO-8859-1"/> <title>Error 500 Async support is not enabled.
