Added multiple log features.

* [Reintroduced](https://github.com/Torxed/archinstall/blob/f64a605449f59c677dff39962f1cb46616d893b7/archinstall.py#L57-L71) log levels
* Created a global log file definition
* Optional support for `python-systemd`'s journald handler.
* Optional file output that has a globally configurable definition, that archinstall will honor in `archinstall.storage['logfile']`.
