mergify[bot] 428cacff88 scans crds table in parallel for finding old labels (bp #13073 ) (#13277 )

* scans crds table in parallel for finding old labels (#13073)

From runtime profiles, the majority time of ClusterInfo::handle_purge
https://github.com/solana-labs/solana/blob/0776fa05c/core/src/cluster_info.rs#L1605-L1626
is spent scanning crds table finding old labels:
https://github.com/solana-labs/solana/blob/0776fa05c/core/src/crds.rs#L175-L197

This can be done in parallel given that gossip thread-pool:
https://github.com/solana-labs/solana/blob/0776fa05c/core/src/cluster_info.rs#L1637-L1641
is idle when handle_purge is invoked:
https://github.com/solana-labs/solana/blob/0776fa05c/core/src/cluster_info.rs#L1681

(cherry picked from commit 37c8842bcb)

# Conflicts:
