SOLR-14776: Precompute the fingerprint during PeerSync (#1814)
After heavy indexing, the call to compute fingerprint takes awhile and slows
the leader election. This commit computes the fingerprint in parallel with
fetching the fingerprint from the other replicas.

> Computing fingerprint can very costly and take time. But the current
> implementation will send requests for getting fingerprint for multiple
> replicas, then on the first response it will then compute its own fingerprint
> for comparison. A very simple but effective improvement here is compute its
> own fingerprint right after send requests to other replicas.
