s3: Add dbwrap_try_fetch_locked
This is designed to spread the load on individual ctdb records to allow upper
layers to do backoff mechanisms. In the ctdb case, do not get the record if a
local lock is already taken. If we are not dmaster, do at most one migrate
attempt.
For the tdb case, this is a nonblocking fetch_locked. If someone else has the
lock, give up.
