    Remove obsolete keepalived PID files before start

    keepalived refuses to start and claims "daemon already started"
    when there is already a process with the same PID as found in
    either the VRRP or the main process PID file. This happens even
    in case when the new process is not keepalived. The situation
    can happen when the neutron node is reset and the obsolete PID
    files are not cleaned before neutron is started.

    This commit adds PID file cleanup before keepalived start.

    Compared to upstream commit, the fixture in test_keepalived was adjusted
    for kilo's version of fixtures package.
