Add a flag for connection command when fetching database credentials

[fernando-villalba]

Description

Currently with civo database credentials we have this:

  -c, --connection-string   show the connection string for the database

Which outputs this

postgresql://civo:[email protected]:5432

This isn't bad, but we can do better.

We need a flag to give a full connection command for the DB so the user can just copy and paste that.

Acceptance Criteria

• Add a flag like this:

civo database credentials --cmd

(flag could be something else if the implementor has better ideas)

• The output of the flag for psql must be this (replacing ip, password, etc):

psql "postgresql://[db-user]:[db-password]@[db-ip]:[dp-port]/postgres?sslmode=require"

• The output for mysql must be this:

mysql --ssl-mode=REQUIRED --host=[managed-db-ip] --port=[db-port] --user=[db-user] --password='[db-password]'

Please not that for the password in the mysql command it needs to have the single quotes because it occasionally uses characters like #

Additionally when the user uses the command on its own like so:

civo database credentials db-name

Add the command to one of the columns
