Performance counter creation is no longer synchronized at startup

Performance counter creation is no longer completed before user code is executed. Sometimes I get messages like this when running sheneos in distributed:

[what]: unknown performance counter: '/counters/messages{locality#1/total}/count/sent' (no create function for performance counter found: /counters/messages{locality#1/total}/count/sent (counter type is not defined): HPX(bad_parameter): ): HPX(bad_parameter)
