Subject: [PATCH] Only if loadbalancer's status is normal then create pool in
 db

When a loadbalancer is in PENDING_UPDATE state, creating a pool with
this lb will return http 409 error with "Invalid state PENDING_UPDATE
of loadbalancer resource LB_ID". But the pool already exists in the
database although the api return this error.

So we shall create a pool in db only if the loadbalancer's state is
normal, wich is consistent with creating listners.
