revlog: use the new Config classes in _testrevlog

the mock object need to follow the new interface. We allow ourself a small
hacky import since this is testing code.

The legacy attribute are still here because some code still use them. We will
drop them when this code is updated.

# Dummy extension that adds a delay after acquiring a lock.
#
# This extension can be used to test race conditions between lock acquisition.
