Add precommit_XXX event for security group and rules
Current BEFORE_CREATE/DELETE/UPDATE event is outside of the DB
transaction. Unlike the precommit primitive in ML2 mech drivers, they
don't work in the same DB transaction of resource, so if we want to
operate the DB in mech driver related to security group, there would be
more unsync issues if we use BEFORE_XXX event directly. Moving the
BEFORE_XXX event inside may also break some current codes, as maybe RPC
call included.
This patch adds new PRECOMMIT_CREATE/DELETE/UPDATE event type for
callback function, and use it in the securitygroup/rules DB transaction.
PRECOMMIT_XXX is in the DB transaction and only purpose is to do DB
operations in its callback. A CallbackFailure will be triggered when
exception comes from the callback of the new event.

Title:
add the new precommit event for security groups
Status in neutron:
Fix Released
Bug description:
Neutron has already been able to make the agentless driver receive the
security
group BEFORE/AFTER event by neutron callback logic. But this logic still
lacks the precommit function, like in Ml2 mechanism driver, which guarantees
that the
mechanism driver DB and neutron DB operation are in the same transaction.
Because the MD may want to have the event callback function and hope its own
DB
operation in the same transaction with neutron securitygroup db.
