The old hkheartbeat variable was changed to the mxs_clock() function that simply wraps an atomic load of the variable. This allows it to be correctly read by MaxScale as well as opening up the possibility of converting the value load to a relaxed memory order read. Renamed the header and associated macros. Removed inclusion of the heartbeat header from the housekeeper header and added it to the files that were missing it.
