[Bug 1479514] [NEW] subnet-update of allocation_pool does not prevent overlap of existing gateway IP

 

Public bug reported:

There are three variations here with the subnet-update command:

1) subnet-update of the gateway_ip  such that the new gateway is placed
in the existing subnet allocaton pool.  This results in
GatewayConflictWithAllocationPools.

2) subnet-update of both the gateway_ip and the allocation_poll .  If
the new gateway IP is located in the new allocation pool, then
GatewayConflictWithAllocationPools is returned.

3) subnet-update of just the allocation_pool.  If the new allocation
pool includes the existing gateway_ip, no error is returned.

Scenario 3 needs to be fixed to return same exception as (1) and (2).
