TommyLike e72f0fdf26 Handle quota in 2 phases when managing resource

Cinder would commit quota twice when managing resource
in a clean environment that the corresponding
'quota_usage' record is empty. This is all because of
we create db entity before reservation, hence the SYNC
mechanism would refresh new record into quota_usage
before actually reserved.

This patch fix this issue by introducing 2 phases
reserve&commit, the latter only intends to update
the actual size.
