Subject: [PATCH] Add API tests for subnet-create with subnetpool

With subnetpool, we can create subnet with subnetpool.
User can specify CIDR or prefixlen for subnet allocation.
If neither is specified, CIDR will be chosen from the
pool using the default-prefixlen of the pool.

Partially-Implements: blueprint subnet-allocation
