Solr CLI should be able to do a node healthcheck

This healthcheck only needs to work for the localhost, but obviously support a customized port.

This healthcheck command should also support a healthcheck type, such as "ready" or "live". The backend API calls for these types can change over time, but "admin/info/health" is a good start for "ready" and "admin/info/system" can be the first implementation for "live".

Future tickets can be spun off to make each implementation better.

These healthchecks should work with TLS and Auth if either is enabled.
