The checks for open ports/ sockets was timinig out after 1 second which
isn't reasonable.

Too many changes in one commit that aren't relevant to each other all
because I didn't commit these for some time and they piled up, exactly
what I shouldn't do.

- Remove some Git submodules. They're not needed.
- Remove the REPREPRO_BASE_DIR environment variable, it's set with
direnv inside that project.
- Use Docker Buildkit.
- Use auto Python interpeter with Ansible, prefer Python3.
- Better ls aliases.
- Netcat aliases to listen and check ports and sockets.
- Aliases and functions for Terraform.
- Use Black to format Python code.
- Show the run duration and exit code in a line before the prompt, maybe
better with Bash earlier than 5.0, where there's an annoying with line
wrapping.
- Valid name for the flatpak_kill shell function.
- Delete user-dirs files, didn't do anything anyway.
- Convert README from reStructuredText to Markdown.
- Don't install gsutil with Python2, use snap to install the Google SDK.
- More pre-commit hooks, update the exiting ones, format the file for
yamllint, Use flake8 from it's repo, the one from the hooks repo is
deprecated.
- Clean the Shore SSH config.
- Add the shared AWS keys to the Endless SSH config.

Back to ElementaryOS, Flatpak is older there.

- No more prerun files, remove said code.
- Set PS1 during __prompt (called by BASH_COMMAND everytime the prompt
is going to be shown).
- Consistent calculation of runduration across __prompt and
__command_notifier.
- Open bug: the exit status is shown until a new command is run.

This reverts commit 208c1bcc. Now all
commands are monitored.

- Use notify-send to notify on finished (successfully or not) long
running commands (all commands, not just those with monitor).
- Move all Bash specifics together, under the if shell==bash clause and
to the end.

- Add region alias for configured (profile) region.
- Add metadata-region for outputting the region from the EC2 metadata
service, moved from .bashrc (no longer exported as AWS_DEFAULT_REGION,
not an issue since it could only be used in EC2 instances and not for
local use, it was there mainly as a reminder for me).
- Add ecr-login instead of a shell alias, works the same.

Because .bashrc was identified as a plain text file (it's not a shell
script), the shell-lint and shellcheck hooks weren't checking it. Add an
explicit hook just for it. Also, fix or silence whatever shellcheck
found.

- Vendored rabbitmqadmin, Bash completion.
- Use gsutil from PyPI, vendored Bash completion.
- Use gcloud from Snap, remove Docker aliases (it just for Linux
anyway).
- on-change, cw, mysqldump-loader Golang apps.
- importlab, remarshal Python apps.

- Added Makefile to download the vendored and binary files.
- Replace gen-ssh-config with the said Makefile.
- Update all sorts of Bash completion files.
- Added `kompose` Bash completion file.
- Replace pythonrc submodule with said Makefile.
- Replace `bfg` shell function with said Makefile (and short shell
alias).
- Update Git hook to use Makefile, remove whatever was removed.
- Added `rc_update` shell alias to force update all said files.
- Added `kind` Golang binary.

- Moved `monitor` from a shell function to a script, now it's callable
without mocking with the shell. Also, added an alias for `monitor` to
expand aliases after it.
- `sudome` is now a shell script instead of a function, now it works
around the `secure_path` option by trying to find the executable in the
path before calling `sudo`. Also, added an alias for `sudome` to expand
aliases after it.
- `__apt-daily` is now a shell script, it probably could have stayed a
shell alias but the quotes failed to pass the entire command to
`/bin/sh` as it was and I couldn't be arsed to solve it.
- Simplified `flatpak-daily`.
- `dd` shell alias is simpler and now the invocation `sudome dd` works
as expected (which was the whole point to begin with).
