Code Issues Proposed changes

Remove upgrade specific info from user facing exception text

Browse Source 
One of the PortUpdateFailed exception usage case introduced by the
bp support-move-ops-with-qos-ports overly chatty about upgrade and
pinned RPC. This message can reach the end user during resize so the
deployment specific information is removed from the exception message
and logged instead. Also a TODO is added that the whole check can be
removed once we bump the compute RPC to 6.0
