Perform the stat check multiple times when checking a storage
...
Instead of only checking once within a timeout, check multiple times
within a timeout.
That means with a timeout of 30 seconds and 3 retries. Each try would
be allowed 20 seconds.

Implement backoff for the circuitbreaker
...
The circuitbreaker now has 2 failure modes:
- Backing off: This will raise the `Gitlab::Git::Storage::Failing`
exception. Access to the shard is blocked temporarily.
- Circuit broken: This will raise the
`Gitlab::Git::Storage::CircuitBroken` exception. Access to the shard
will be blocked until the failures are reset.
