Merge #19658: [rpc] Allow RPC to fetch all addrman records and add records to addrman

Browse Source 
37a480e0cd [net] Add addpeeraddress RPC method (John Newbery)
ae8051bbd8 [test] Test that getnodeaddresses() can return all known addresses (John Newbery)
f26502e9fc [addrman] Specify max addresses and pct when calling GetAddresses() (John Newbery)

Pull request description:

  Currently addrman only allows a maximum of 1000 records or 23% of all records to be returned in a call to `GetAddr()`. Relax this limit and have the client specify the max records they want. For p2p, behaviour is unchanged (but the rate limiting is set inside net_processing, where it belongs). For RPC, `getnodeaddresses` can now return the complete addrman, which is helpful for testing and monitoring.

  Also add a test-only RPC `addpeeraddress`, which adds an IP address:port to addrman. This is helpful for testing (eg #18991).
