Bojan Čekrlić 9b1902c047 Larger refactoring of the codebase + DKIM_SELECTOR
Summary
^^^^^^^

This commit refactors the code base to be more manageble and
prepares the groundwork for tests.

Refactoring
^^^^^^^^^^^

Files are now moved to subdirectories, all for the sole purpose of
easier management. Tests live in their own folders, as well as configs
and other files.

Test framework
^^^^^^^^^^^^^^

Two new important scripts/directories are available:
- `unit-tests.sh` / `/unit-test` which executes unit tests across shell
  scripts, and
- `integration-test.sh` / `integration-tests`, which spins up the
  container and tries to send the email.

Both tests use the [BATS](https://github.com/sstephenson/bats) framework
for testing. To create a new test, simply drop a `.bats` file into a
corresponding directory.

Functions have been extracted into `common-run.sh`, to be able to test
them independently.

DKIM_SELECTOR
^^^^^^^^^^^^^

It is now possible to specify a DKIM selector to use (instead of
the default "mail"). See `README.md` for more details.

JSON logging
^^^^^^^^^^^^

WIP: rsyslog will now output JSON logs. This is especially important
if you plan on deploying the image into Kubernetes, as [Prometheus](https://prometheus.io/)
can handle logs in JSON much easier.

TODO: Make this an optional feature, to not confuse existing users.
