Fix wd restart behaviour

  * run_wd_keepalive option - required, to be clearly catched by
    salt service reload\restart
    Set it by default=1, on service lvl.
  * Add possibility to configure ping\load params
  * Remove kernel module manipulations:
    - Passing params to conf w\o reboot - makes no sense
    - Params should be also passed to sysfs, if needed.
      Those funtion should be done via linux-formula
      Readme updated
  * Mics: fix schema,update to latest run_tests, fix .travis tests
  * Remove WA for LP:1448924 since fix already released.
