==================
- Load croud commands from a ``croud_commands`` `entry points
<https://setuptools.readthedocs.io/en/latest/setuptools.html#dynamic-discovery-of-services-and-plugins>`__
section.
- Added a tabular format to the list of possible output formats in subcommands.
- Added subcommand `me` that allows to print info about the current
logged-in user.
- Added subcommand `login` that allows to login to https://cratedb.cloud
using OAuth. It will open a browser to start the authentication process.
- Added a subcommand `logout` that clears the stored login token, and clears the
OAuth session
- The environment used to logged to in is now stored in config, so it is only
necessary to provide the ``--env`` flag on the ``login`` subcommand
