LXC images with stable apkg

See merge request !134

deb: only require build-essential on system-setup

See merge request !133

arch: add manjaro to supported distros

See merge request !135

pacman -S defaults to reinstalling existing packages.

See ci/lxc/README.md

devscripts are convenient to have, but they're big so only require
build-essential package on debian systems instead.

test-dep: fix parsing of test deps

See merge request !132

When deps list in control ended with ',', for example

    Depends:
     foo,
     bar,

parsing returned an extra empty string breaking `apkg test-dep`.

docs: add new apkg users

See merge request !131

CI: update apt db before creating Knot DNS archive

See merge request !130

CI: add AlmaLinux 9 image alma-9

See merge request !129

Move EL (centos, rocky, alma) jobs bellow fedora for better file
structure.

Remove hard dep on python3-blessings in RPM because it's not
available from EPEL 9. apkg can run fine without it, just no colors.

docs: update apkg overview

See merge request !128

docs: update news for upcoming 0.4.0

See merge request !127

for consistency in CLI help output.

cache: refactor cache with targets and config

Closes #73

See merge request !119

There are now 3 cache targets along with associated config options:

* cache.local
* cache.remote
* cache.source

cache.source is only enabled when VCS is available, other cache
targets are unaffected by VCS and are enabled by default.

Caching apkg commands require following cache targets:

* make-archive: source
* get-archive: remote
* srcpkg: local (archive), source (templates unless --upstream)
* build: local (source package)

This leads to cache only being disabled for relevant commands working on
project source when VCS isn't available as opposed to disabling all
caching.

Logging was vastly improved to get useful cache information when using

    apkg -L verbose $COMMAND

Docs were expanded with a new cache.md as well as upated with clearly
worded requirements for working cache (VCS and proper make_archive_script).

Simple test on examples/minimal-no-git is included in
ci/tests/test_apkg.py for testing operation without VCS.

Closes: #73

Also add similar cache.hash_path() and common.path_checksum() to compute
checksum of multiple file paths as strings (as opposed to file contesnts).

This is required for proper caching on multiple input files.

Get rid of unneeded cache_name, only use simple key:value store.

A minimal example apkg project with a single executable bash script.

`apkg info cache` now displays cache contents and logs cache file
location for convenience and easier debugging.

Also align similar `apkg info config` to have consistent output

I'm not in the mood to really try understanding what's the matter,
but this change seems to work OK.

CI: allow nix jobs to fail

See merge request !126

nix jobs are often blocking MRs due to unrelated issues which I find
hard to debug/fix as I'm not yet very familiar with Nix and it works
very differently compared to other platforms/package managers.

Allow failure for nix jobs until they reach reliability of other jobs.

setup: add setuptools to requirements.txt

See merge request !125

Aside from build, setuptools are used by minver during sdist
so they're required to create apkg archives (make-archive) as well.

tests: remove old dummy test

See merge request !124

This was used to bootstrap unit tests, but there are now real ones so
it's no longer needed.

Revert "setup: require jinja<3.1 to prevent breakage"

See merge request !123

This reverts commit d120a385.

The change introduced unwanted side-effects which would only get worse
with time.
