util: remove unwanted fields from bitcoin-cli -getinfo

In accordance with #17314, Removing noisy fields from -getinfo. Fields removed: protocolversion, walletversion and keypoololdest. In addition to changing bitcoin-cli -getinfo, there is another change to test/functional/interface_bitcoin_cli.py. This change deletes tests that utilize removed -getinfo calls.
