Enhancement Task

In a large cluster, when PD is restarted, it cannot be the leader only when it finishes loading all regions into memory. But this process will be slow if the number of regions is large, which could affect the availability of TiDB. We need to accelerate this process or use other mechanisms to reduce the unavailable time as much as possible.

After a discussion, we are going to add a new API to get the synchronized state and let TiUP do some checks to reduce the unavailable time.
