cli: initial introduction of 'kallithea-cli' command

This commit adds a command 'kallithea-cli' that intends to replace the
existing set of 'gearbox' commands that relate to setting up kallithea.
Gearbox would still be used for 'gearbox serve', but other commands like
'make-config', 'setup-db', etc. would be converted to 'kallithea-cli'
commands.

The python package 'Click' is used to generate the CLI. Using decorators,
this package makes it very easy to generate a CLI out of simple methods.
See: http://click.pocoo.org/7/

Using Gearbox for custom commands is possible, but documentation on this
topic is limited. As the added value of Gearbox for that use case is not
clear, we can well switch to something else if it seems better/easier.
