julian 8bc60e42a8 Extend distribution_check role to account for Ansible changes reg. facts
Somewhere between ansible [core 2.14.4] and ansible [core 2.15.0] the
logic for the distribution_version Ansible fact got changed. With the
newer Ansible version Debians distribution_version gets reported as 11.7
as opposed to getting reported as 11 with the old Ansible version. To
still allow for useful distribution checks, extend the
distribution_check role by allowing the specification of
distribution_major_versions and distribution_releases as well.
This way you can check for an Ubuntu version by using
distribution_version (which for example resolves to 18.04, while
distribution_major_version would resolve to 18 in that case) and check
for a Debian version by using distribution_major_version (which for
example resolves to 11, while distribution_version would resolve to 11.7
in that case).

# Role `distribution_check`
This role checks if the distribution of the hosts is supported (part of the provided distribution support spec.) and fails if it's not.
If a hosts distribution and either an accompanying distribution version, major version or release is supported, the role doesn't fail for the host in question.
## Required Arguments
For the required arguments look at the [`argument_specs.yaml`](./meta/argument_specs.yaml).
## `hosts`
The `hosts` for this role need to be the machines for which you want to make sure their distribution is supported.
