    Log INFO message when setting admin state up flag to False for OVS port
    
    Disabling admin state can cause confusion in OVS agent logs as to why
    VLAN 4095 is set to a particular port. This commit adds an extra INFO
    log message when admin state is disabled. There is no log emitted
    upon enabling admin state as there is already a detailed log entry
    logged in treat_devices_added_or_updated() function.

Title:
  Setting admin_state down on port  produces no logs

Status in neutron:
  Fix Released

Bug description:
  Tried to check how admin_state down affects HA ports.
  Noticed that management data between them stoped and cause them to become master. Although traffic to connected floating IP remain working.
  Problem is: no log on OVS agent idicated why it's processing a port update or why it's setting it's VLAN tag to 4095.
  (06:39:44 PM) amuller: there should be an INFO level log saying something like: "Setting port admin_state to {True/False}"(06:39:56 PM) amuller: with the port ID of course

  Current log:
