    Wait to ipv6 accept_ra be really changed by L3 agent
    
    In functional tests for L3 HA agent, like e.g.
    L3HATestFailover.test_ha_router_failover
    it may happen that L3 agent will not change ipv6 accept_ra
    knob and test fails because it checks that only once just
    after router state is change.
    
    This patch fixes that race by adding wait for 60 seconds to
    ipv6 accept_ra change.

Title:
  _assert_ipv6_accept_ra method should wait until proper settings will
  be configured

Status in neutron:
  Fix Released

Bug description:
  This method is defined in
  neutron/tests/functional/agent/l3/framework.py and it should use
  wait_until_true to avoid potential race conditions between test
  assertions and what L3 agent is doing.

  It seems that e.g. in http://logs.openstack.org/61/659861/1/check
  /neutron-functional/3708673/testr_results.html.gz there was such race
  which caused test failure.
