The original `MinerInfo.peer_id` field of the storage miner is no longer applicable

[0xbillw]

Cause

The current version of MinerInfo.peer_id represents the ID of the storage-miner P2P node. Due to the change of data transmission protocol for storage-miner, this field no longer has practical significance. On the other hand, the information used to represent the endpoint of the storage-miner borrows this field, resulting in improper expression of business semantics and making it difficult for future code maintenance.

Advices

1. Deprecate the MinerInfo.peer_id field
2. Add a field similar to endpoint to represent the API endpoint of the storage miner
