use notifies :restart

somewhy notifies :reload does not even invoke initscript, and as reload
and restart actions are identical in pld this change is okay

i thought the problem is identical as #13, but was not, `:immediately` did not help
also tried to add `supports [:reload]` to service the reload methods just were not called out. tried to debug in chef, but got lost quite soon.

anyway, this is safe to add as code what gets invoked is identical
