[Speedup sync]synced mainnet and wallet db files migaration between local network machines.

[HomeLH]

1. On the full synced machine, stop chia deamon chia stop -d all. Check dbs files at ~/.chia/mainnet/db and ~/.chia/mainnet/wallet/db, make sure that only exists blockchain_v1_mainnet.sqlite, not *.sqlite-wal, *.sqlite-shm. If exists *.sqlite-wal, *.sqlite-shm, try chia start famer, then chia stop -d all.
2. On the target machine, make sure no chia process is running. Remove all files at ~/.chia/mainnet/db and ~/.chia/mainnet/wallet/db.
3. Copy source machine ~/.chia/mainnet/db/blockchain_v1_mainnet.sqlite ~/.chia/mainnet/wallet/db/blockchain_wallet_v1_mainnet_*.sqlite into target machine ~/.chia/mainnet/db/blockchain_v1_mainnet.sqlite ,~/.chia/mainnet/wallet/db/blockchain_wallet_v1_mainnet_*.sqlite
   on linux, use scp with scp user@host:/home/user/.chia/mainnet/db/blockchain_v1_mainnet.sqlite ~/.chia/mainnet/db/blockchain_v1_mainnet.sqlite.
4. If "pool_list" section in your config.yaml is missing your current pool settings, it will produce "Exception from 'wallet' Unclosed client session & Unclosed connector". Slove this problem with [BUG]Exception from 'wallet' Unclosed client session & Unclosed connector #7210 (comment). Just copy the whole "pool_list:" section from old machine to the new one and it works fine. Check it with chia plotnft show
5. Check 'chia show -cs`, good luck
