Description

When adding lots of range partitions, all tablet server crashed with the following error:

F0308 14:51:04.109369 12952 raft_consensus.cc:1985] Check failed: _s.ok() Bad status: Runtime error: Could not create thread: Resource temporarily unavailable (error 11)

Tablet server should handle error/failure more gracefully instead of crashing.
