cmdserver: recreate mq object on runcommand in case queue path was changed
repo.mq needs to be recreated after queue path change. Since there is little
benefit to keep invalidated mq object, it always delete repo.mq.
cmdserver: reload mq on each runcommand request to avoid corruption
If mq was changed by another process, command server should invalidate caches.
Otherwise, mq status would go wrong.
localrepo: add hook point to invalidate everything on each command-server run
MQ extension will wrap this function to invalidate its state.
repo.invalidate cannot be wrapped for this purpose because qpush obtains
repo.lock in the middle of the operation, triggering repo.invalidate. Also,
it seems wrong to obtain lock earlier because mq data is non-store parts.
