Update MicroCloud look and feel (#505)

Uses https://github.com/charmbracelet/lipgloss to implement tables and
questions in MicroCloud.

* There is much more colour in the CLI now. This can be disabled with
the `NO_COLOR` environment variable or the `--no-color` flag.

* `make build-test` has been added to the Makefile, which builds
MicroCloud with different input/output sources to work with the system
tests. `TEST_CONSOLE=1` only works with this build tag now.

* the test tag also replaces the EFF wordlist with a predictable 'a a a
a' to reduce complexity in the test script and make debugging easier.

* package dependencies for the old implementation and test console have
been removed.
 
* there is a new file at `/var/snap/microcloud/common/test-output` that
is generated with the test build tag and `TEST_CONSOLE=1` to show how
each question interpreted the pre-defined input.
