`fides status` command should also include database health

[ThomasLaPiana]

Is your feature request related to a specific problem?

The fides status command returns healthy but the database is in an unhealthy state

Describe the solution you'd like

This command should run a small query to verify that the database is reachable and functioning, with the output looking something like the following:

Getting server status...
Server is reachable
Client/server version match
Version: 1.8.2
Database: Healthy
