    Throttle collectd OVS interface plugin startup wait log

    This update turns a flooding failure log into a single
    waiting log while the collectd OVS interface plugin
    initialization sequence waits for a running ovs daemon.

    A few pep8 long line warning are fixed.

    Test Plan:

    PASS: Verify plugin behavior of compute system install without Openstack
    PASS: Verify plugin behavior in AIO-SX with Openstack
    PASS: Verify plugin failure handling and recovery with Openstack
                 Note: the ovs-vswitch pmon conf file was changed to allow
                 process failure recovery to verify the plugin was able to
                 handle transition from not running/waiting to running once
                 process started.
    PASS: Verify plugin failure handling when ovs-vswitchd process fails.
                 Note: pmond does not try and recover and the following
                 collectd log is produced every 10 seconds.
                 'err ovs interface plugin failed to dump ports br-phy1 desc'
