This change implements and enables by default quorum support
for rabbitmq as well as providing default variables to globally tune
it's behaviour.
In order to ensure upgrade path and ability to switch back to HA queues
we change vhost names with removing leading `/`, as enabling quorum
requires to remove exchange which is tricky thing to do with running
services.

With update of ansible-lint to version >=6.0.0 a lot of new
linters were added, that enabled by default. In order to comply
with linter rules we're applying changes to the role.
With that we also update metdata to reflect current state.

With ansible-core 2.13 it tries to substitude package resolution in apt
module.
However git-core is used in Debian as transitional name, but ansible
tries to select it and provide version, which is not correct behaviour.
But since git-core is not really valid anyway, we just replace it
to workaround ansible's imperfectness.

Previous to this change the uwsgi config had virtualenv include /bin, leading to $venv/bin/bin in execution

All references to Gentoo, SUSE, Debian stretch and Centos-7 are removed.
Conditional tasks, ternary operators and variables are simplified where possible
OS specific variables files are generalised where possible

We use the same condition, which defines against what host some "service"
tasks should run against, several times. It's hard to keep it the same
across the role and ansible spending additional resources to evaluate
it each time, so it's simpler and better for the maintenance to set
a boolean variable which will say for all tasks, that we want to run
only against signle host, if they should run or not now.

Move service to use uWSGI role instead of iternal task for uwsgi
deployment. This aims to ease the maintenance of uWSGI and speedup
metal deployments as the same uwsgi environment will be used
across all services.

In order to radically simplify how we prepare the service
venvs, we use a common role to do the wheel builds and the
venv preparation. This makes the process far simpler to
understand, because the role does its own building and
installing. It also reduces the code maintenance burden,
because instead of duplicating the build processes in the
repo_build role and the service role - we only have it all
done in a single place.
We also change the role venv tag var to use the integrated
build's common venv tag so that we can remove the role's
venv tag in group_vars in the integrated build. This reduces
memory consumption and also reduces the duplication.
This is by no means the final stop in the simplification
process, but it is a step forward. The will be work to follow
which:
1. Replaces 'developer mode' with an equivalent mechanism
 that uses the common role and is simpler to understand.
 We will also simplify the provisioning of pip install
 arguments when doing this.
2. Simplifies the installation of optional pip packages.
 Right now it's more complicated than it needs to be due
 to us needing to keep the py_pkgs plugin working in the
 integrated build.

This removes the systemd service templates and tasks from this role and
leverages a common systemd service role instead. This change removes a
lot of code duplication across all roles all without sacrificing features
or functionality. The intention of this change is to ensure uniformity and
reduce the maintenance burden on the community when sweeping changes are
needed.
The systemd journal would normally be populated with the standard out of
a service however with the use of uwsgi this is not actually happening
resulting in us only capturing the logs from the uwsgi process instead
of the service itself. This change implements journal logging in the
service config, which is part of OSLO logging.

In order to make it easier to differentiate between the lists of
python packages, distribution packages, downloaded packages,
package pins and other similar variables the variable names are
being changed to ensure that they have a more explicit suffix
that defines the purpose and makes the naming more consistent.
This is to facilitate a lookup plugin which will be able to look
up all the package lists and present them as a consolidated piece
of data which may be used for artifact preparation.
