Info
As part of SERVER-27659 we moved from an in-memory rbid to one stored in a collection, which requires a global IS lock. This makes commands that didn't used to require any global lock require one to fill in the replSet metadata. This seems to be causing spurious stepdowns in some of our tests. Additionally, it prevents FTDC from capturing data while the global lock is held or pending.

Message: SERVER-28988 add ReplicationProcess
This class is intended to hold replication state in a secondary node related to
the copying and applying operations from the sync source.
This initial implementation holds a cached copy of the rollback ID only.

We should definitely cache the RBID. schwerin and I discussed this and we are proposing new object attached to the ServiceContext that will be used for caching the rollback ID for now but may be expanded to hold other state for replication.
