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.
