URL: https://github.com/apache/knox/pull/755
## What changes were proposed in this pull request?
CM's `PollingConfigurationAnalyzer` ignores events of service types that
have no `ServiceModelGenerator` instances to avoid redundant topology
redeployment.
## How was this patch tested?
Updated JUnit tests and executed comprehensive manual testing in a live CM
cluster with lots of services.

> The {{PollingConfigurationAnalyzer}} does not filter the events received from
> CM and tries to find the source service in the configuration cache, which of
> course won't be possible due to the above causing non-proxied services to be
> handled as services newly enabled for proxying.
