Proposed changes

Staking information was stored in misc db after state-db migration was developed. It is possible not to retrieve staking information on some past blocks. This PR add an API to sync staking information from other peers to update staking information on misc db.

Since staking information won't be validated, it would fetch the data from trusted node given by node id. Also, the boundary was given as well so that only a few staking information can be retrieved in the boundary.
