Add bash-completion and toltec-completion packages (#277)

* Add bash-completion and toltec-completion packages

* Fix format issues

* Small fixes and update copyright year

* Revert "Fix format issues"

This reverts commit 83e26b6.

* Fix depends keyword in package file

* Fix some shellcheck issues and ignore others

Reasoning was added to the top of the file.

* Remove source hint from toltec-completion

* Compromize more to make shfmt happy

Seems that shfmt complains even after I disabled
the shellformat rule. Does shfmt not use shellformat?

* Ignore another check

The completions should not be suspect to the problems
listed here: https://www.shellcheck.net/wiki/SC2207

* Add completions for toltecctl

The command is still a PR (#356).
