ARTEMIS-2991 Removing HttpAcceptorHandler from HttpKeepAliveRunnable when

> Leak of HttpAcceptorHandler instances when using websocket connections

> Affects Versions: 2.9.0, 2.10.0, 2.10.1, 2.11.0, 2.12.0, 2.13.0, 2.14.0,
> 2.15.0, 2.16.0

> Time Spent: 2h 10m
> Remaining Estimate: 0h
>
> We are running Artemis 2.9.0 and we noticed the memory grows continuously
> after getting a heap we discovered there are a leak of multiple instances of
> type org.apache.activemq.artemis.core.remoting.impl.netty.HttpAcceptorHandler
> which are keep in a list inside
> org.apache.activemq.artemis.core.remoting.impl.netty.HttpKeepAliveRunnable.
>
> Those instances are removed in the channelInactive method but this method is
> not called because when doing the upgrade to websocket the handler is removed.
>
> Proposals:
> 1) In the upgrade clean up the reference for the HttpAcceptorHandler before
> removing the handler.
> 2) If option 1 does not work because that threads also send the keep alive
> for websocket, I could use the channelInactive from websocket handler to
> later unregister the handler
