    Revert haproxy restart primitive back to reload

    This commit switches back haproxy configuration reload
    to use reload command of OCF script. Otherwise, for Ubuntu
    since kernel 3.9 haproxy due to some race condition in
    OCF script may start two times with different configs
    as it uses REUSEPORT socket option. By using reload
    we ensure that there is always one process on the listening
    socket which has the latest config.

    This fix is may be partial as we may also require additional work
    on OCF script to introduce additional checks on pids and pidfiles.
    It can also be tracked as a partial duplicate of the bug related
    to better handling of processes manipulations in OCF scripts.
