David Turner 86b1a07887 Log leader and handshake failures by default (#42342) ...

Today the `LeaderChecker` and `HandshakingTransportAddressConnector` do not log
anything above `DEBUG` level. However there are some situations where it is
appropriate for them to log at a higher level:

- if the low-level handshake succeeds but the high-level one fails then this
  indicates a config error that the user should resolve, and the exception
  will help them to do so.

- if leader checks fail repeatedly then we restart discovery, and the exception
  will help to determine what went wrong.

Resolves #42153
