Commit 35f6d827d04ef2d898d780c921d841047bb7fa4a in geode's branch

GEODE-2534 concurrently started locators fail to create a unified system
GMS services were being installed in the locator before they were started,
causing the locator to not know its own member ID. This caused the
concurrent startup registry to not contain its member ID, allowing
FindCoordinatorResponses to be incorrect.

> Project: Geode
> Issue Type: Bug
> Components: locator
> Reporter: Bruce Schuchardt
>
> During startup a locator responded to a "find coordinator" request before
> knowing its own identity. This caused it to respond differently to
> subsequent requests during concurrent locator startup. As a result it
> created its own distributed system while the locator that received the
> initial response created a different one.
