GEODE-7435 - Improve performance of GMSMembershipManager.handleOrDefe… (#4373)
* GEODE-7435 - Improve performance of GMSMembershipManager.handleOrDeferMessage
Modified the method to avoid synchronization unless we're in an initialization
phase.
While initializaing we synchronize and queue messages unless we're told the
queue has been drained.
* re-enabled check in handleOrDeferMessage
* moved return statement into startup-queue block
* empty commit

> GMSMembershipManager.handleOrDeferMessage serializes all threads on a lock
> to {{startupLock}}.
> Find lock free mechanism to synchronize these threads only when we are int
> "startup" phase. After this phase there should be no reason to synchronize
> and serialize calls.
> Bechmark profiling shows 60% of thread time is spent waiting for this monitor
> after correcting GEODE-7434.
