[PATCH 1/2] agent_msg_filter_process_data(): always return _MONITORS_CONFIG

[Jonathon Jongsma <jjongsma@xxxxxxxxxx>]

Instead of having a check inside of the agent message filter to see
whether the RedDispatcher should use the client monitors config, move
this check out to the caller and always return
AGENT_MSG_FILTER_MONITORS_CONFIG for monitor configuration messages.
This simplifies the responsibilities of the message filter (it no longer
has to obtain a reference to the dispatcher to determine how to filter
messages) and also prepares the way for the caller to determine whether
a particular message was a MonitorsConfig message (which will be useful
in a future commit)
