* Decouple role kubespray-defaults from download

Avoids doing re-importing the download role on every invocation of
kubespray-defaults (and skipping everything).

This has a measurable effect on playbook performance.

* Update docs refering to moved download defaults

Molecule 5.0 require ansible-core 2.12.10.
So this commit we update ansible-core from 2.12.5 to 2.12.10.
We also drop supporting two ansible-core version. Also we now use the "oldest"
still supported ansible-core version as both 2.11 is EOL and not
supported by molecule.



tests/molecule: remove linting in molecule to support molecule 5



tests/molecule: remove role name check for molecule 5 support

Kubespray doesn't use ansible galaxy style naming so we have to disable
that check.



contrib/inventory_builder: fix tox.ini for tox4



tests/molecule: fix get_playbook in testinfra tests



tests: upgrade most tests requirements

Exclude ansible-lint for now, I will do that in a separate PR.



tests/molecule: force kvm driver option

If we don't do this it fallbacks to qemu emulated on our CI for some
reasons.

Update Dockerfile

Reducing the number of layers, increasing readability, reducing the size of the image (how much I can’t check, it’s impossible for me to build due to the unavailability of the vagrant repository)

* Update fedora35 vagrant box url

Proposed workaround in comment: https://github.com/pypa/pip/issues/10219#issuecomment-887337037
Setting LANG only prior to launching pip fixes the issue with a successful build

using --no-cache-dir flag in pip install ,make sure downloaded packages
by pip don't cached on system . This is a best practice which make sure
to fetch from repo instead of using local cached one . Further , in case
of Docker Containers , by restricting caching , we can reduce image size.
In term of stats , it depends upon the number of python packages
multiplied by their respective size . e.g for heavy packages with a lot
of dependencies it reduce a lot by don't caching pip packages.
