Version detection on Ubuntu 22.04

[danielsreichenbach]

Using this role with default settings on Ubuntu 22.04 will cause an error when executing the Set HAProxy version. task due to the version reported by haproxy -v being different.

What is happening

When querying the version - not sure if this is because of Ubuntu 22.04 or HAProxy 2.x - the version string will come back as

HAProxy version 2.4.14-1ubuntu1 2022/02/28 - https://haproxy.org/

Fixing it

A temporary fix for the would be to simply modify the task to look for a different version string like

- name: Set HAProxy version.
  set_fact:
    haproxy_version: '{{ haproxy_version_result.stdout_lines[0] | regex_replace("^HAProxy version ([0-9]\.[0-9]).*$", "\1") }}'

If the HAProxy version string is different between versions, it might be an idea to have variables per OS-Release to parse this.

I ran into the same issue when trying to deploy HaProxy 2.4 on AlmaLinux 9 with the resulting exception.

An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ansible.errors.AnsibleFilterError: Version comparison failed: '<' not supported between instances of 'str' and 'int'

Here is some example version tags which should match the modified regex in the PR.
HA-Proxy version 1.5.18 2016/05/10 HAProxy version 2.4.14-1ubuntu1 2022/02/28 - https://haproxy.org/

The linked PR with the updated regex resolved my issue and should retain backwards compatibility.

I've added a new pull request that should make the version detection a little bit more dynamic as well.
