Better handling of resize issues

Populating flavor details from prep.end turns out to be a bit
too early. If the compute is restarted before the resize has
finished the instance will still be the old size. Thus, an exist
after that will be for the old (and actual) size of the instance.

Fixing logging

First, setting up the default logger name for worker and verifier.
Without this, logging from the reconciler and the database api
will end up in stacktach-default. This would mean both the
verifier and worker will be attempting to rotate that log file,
thus locking themselves.

Second, using the child logging process when calling the
info/warn/error functions directly in stacklog. Othweise this will
cause the callers to get or create the parent logger process.
