In order to check if a replica needs to be rebootstrapped, we need to
know the vclock of the oldest WAL stored on the master, but the garbage
collector works with signatures and hence can't report the vclock it was
last called for. Actually, all gc users have a vclock and can pass it
instead of signature so it's pretty easy to switch garbage collection
infrastructure to vclock.

Pushed, with a small follow-up.
