    make floating IP specification test robust to races
    
    The get_unused_ip function returns an address that isn't in use on
    the network at the time it's called. However, by the time the caller
    uses it, it may have been allocated to another concurrent test if
    the network is shared or external.
    
    The test_create_floatingip_with_specified_ip_address test creates
    a floating IP with an unused IP on the external network, which has
    lots of activity on it from other tests so it would occasionally
    have its address taken by another test.
    
    This patch just catches the in use error and tries again with a
    new IP.

Title:
  test_create_floatingip_with_specified_ip_address is racey

Status in neutron:
  Fix Released

Bug description:
  test_create_floatingip_with_specified_ip_address gets an unused IP
  address and then tries to use it for an operation. The issue is that
  it gets it from an external network that other tests may be allocating
  ports from. So it can grab an IP and then another test can allocate a
  port that gets that IP before it tries it floating IP creation. In
  this case the floating IP creation will fail:

  Details: {u'message': u'Unable to complete operation for network
  477f7fb6-aea4-470c-82ca-c05936264e2e. The IP address 172.24.5.8 is in
  use.', u'detail': u'', u'type': u'IpAddressInUse'}
