Review comment:
*THREAD_SAFETY_VIOLATION:* Read/Write race. Non-private method
`ZkStateReader.getLeaderUrl(...)` indirectly reads without synchronization from
`cloud.UrlScheme.INSTANCE.urlScheme`. Potentially races with write in method
`ZkStateReader.forciblyRefreshAllClusterStateSlow()`.
Reporting because another access to the same memory occurs on a background
thread, although this access may not.
