We saw in the Geo testbed where a misconfigured Gitaly node would receive many
gRPC timeouts when a worker attempted to sync a repository on specific
shards. Until direct filesystem access is eliminated from GitLab, we now
perform an additional health check via a gRPC ping to ensure each shard has a
responsive Gitaly server.
