* Remove leftover files for Coreos

Coreos was replaced by flatcar in 058438a2 but the file was copied
instead of moved.

* Remove workarounds for resolved ansible issues

* boostrap: Use first_found to include per distro

Using directly ID and VARIANT_ID with first_found allow for less manual
includes.
Distro "families" are simply handled by symlinks.

* boostrap: don't set ansible_python_interpreter

- Allows users to override the chosen python_interpreter with group_vars
  easily (group_vars have lesser precedence than facts)
- Allows us to use vars at the task scope to use a virtual env

Ansible python discovery has improved, so those workarounds should not
be necessary anymore.
Special workaround for Flatcar, due to upstream ansible not willing to
support it.

* project: update all dependencies including ansible

Upgrade to ansible 7.x and ansible-core 2.14.x. There seems to be issue
with ansible 8/ansible-core 2.15 so we remain on those versions for now.
It's quite a big bump already anyway.

* ansible-lint: disable various rules after ansible upgrade

Temporarily disable a bunch of linting action following ansible upgrade.
Those should be taken care of separately.

no_proxy is a pain to get right, and having proxy variables present causes issues
(k8s components get proxy configuration after upgrade, see #7100)

It's better to only configure what require proxy:
- the runtime (containerd/docker/crio)
- the package manager + apt_key
- the download tasks

Tested with the following clusters
- 4 CentOS 8 nodes
- 1 Ubuntu 20.04 node
