Title:
  add interface doesn't select the first free IP from range

Status in neutron:
  New

Bug description:
  When adding a router interface to network, the interface should get
  the first free IP address from the subnet (/24).

  Version-Release number of selected component (if applicable):

  
  How reproducible:
  100%

  Steps to Reproduce:
  1. create router "test_router"
  2. create network "test_net"
  3. in test_net create subnet "test_subnet":
  net address 10.0.0.0/24
  IPv4
  checkDisable gateway
  click to Create
  4. Network topology, click to router, Add interface, select "test_net: 10.0.0.0/24 (test_subnet)", leave IP address empty, submit the dialogue
  5. red popoup is displayed: "Error: Failed to add_interface: Bad router request: Subnet for router interface must have a gateway IP" - it's valid behaviour so far
  6. networks - click to "test_net" row, edit subnet "test_subnet":
  uncheck Disable gateway,
  set gateway IP 10.0.0.1,
  check enable DHCP (is already checked by default),
  allocation pool: 10.0.0.2,10.0.0.254
  hit Save button
  7. Network topology, click to router "test_router", Add interface, select "test_net: 10.0.0.0/24 (test_subnet)", leave IP address empty, submit the dialogue

  
  Actual results:
  Adding interface is trying to use first IP address from the subnet range, but it's already used as gateway, so red popup is displayed instead:
  Error: Failed to add_interface: Unable to complete operation for network 490131be-13e9-49b8-b515-6d2dec8847da. The IP address 10.0.0.1 is in use.

  Expected results:
  The first unoccupied address is selected automatically.

  Additional info:
  If is new subnet created with gateway IP from beginning, router port is created successfully and it picks the same IP as is defined as subnet gateway
