This patch updates the ouput of the list-plugins command.
This also adds the ability to show the available plugins
to install that are published packages on pypi.org.
This also shows the list of installed packages from pypi.org
This patch updates the healthcheck command to not require
the aprsd.yml config file to exist. The healthcheck
calls a running aprsd, collects the stats to determine if it's
healthy.
This patch refactors the cli to incorporate
the dev, send-message, listen commands into the main aprsd app.
This also moves the command line completion installer/show into
it's own subgroup.
