Add support to Ubuntu 20.04 #813

Starting in version 20 Python 2 packages, specially python-psycopg2 required by geerlingguy.postgresql, are no longer part of the distro and we have to work with their versions for Python 3. My first attempt to get this done was by setting the `ansible_python_interpreter` to something like: ``` ansible_python_interpreter: "/usr/bin/python{% if ansible_distribution_major_version < '20' %}2.7{% else %}3{% endif%}" ``` But it dind't work because at the time `ansible_python_interpreter` needs to be evaluated `ansible_distribution_major_version` still is undefined. This is the reason I'm going for this particular more creative solution. In the future, when the project maintainers decide to end support for Ubuntu 16, this solution should not be necessary and we can just work with Python 3 in Ubuntu 18 and 20.

This package no longer exists and was causing the following error: ``` TASK [common : install base packages] ********************************************************************************************************************************************* fatal: [local_vagrant]: FAILED! => {"changed": false, "msg": "No package matching 'python-psycopg2' is available"} Tuesday 14 June 2022 14:31:23 -0300 (0:00:00.361) 0:00:12.428 ********** ```

This version adds support to Ubuntu 20 while still supports 16 and 18. Fixes the following error present when running in Ubuntu 20: ``` TASK [geerlingguy.postgresql : Include OS-specific variables (Debian).] *********************************************************************************************************** fatal: [local_vagrant]: FAILED! => {"ansible_facts": {}, "ansible_included_var_files": [], "changed": false, "message": "Could not find or access 'Ubuntu-20.yml'\nSearched in:\n\t/home/manzo/workspace/Camar inhaManzo/ofn-install/community/geerlingguy.postgresql/vars/Ubuntu-20.yml\n\t/home/manzo/workspace/CamarinhaManzo/ofn-install/community/geerlingguy.postgresql/Ubuntu-20.yml\n\t/home/manzo/workspace/Camarinh aManzo/ofn-install/roles/dbserver/vars/Ubuntu-20.yml\n\t/home/manzo/workspace/CamarinhaManzo/ofn-install/roles/dbserver/Ubuntu-20.yml\n\t/home/manzo/workspace/CamarinhaManzo/ofn-install/community/geerlinggu y.postgresql/tasks/vars/Ubuntu-20.yml\n\t/home/manzo/workspace/CamarinhaManzo/ofn-install/community/geerlingguy.postgresql/tasks/Ubuntu-20.yml\n\t/home/manzo/workspace/CamarinhaManzo/ofn-install/playbooks/v ars/Ubuntu-20.yml\n\t/home/manzo/workspace/CamarinhaManzo/ofn-install/playbooks/Ubuntu-20.yml on the Ansible Controller.\nIf you are using a module and expect the file to exist on the remote, see the remote _src option"} Tuesday 14 June 2022 14:51:16 -0300 (0:00:00.015) 0:08:08.065 ********** ```

This is a kind of a generic memory error that I could not find the actual cause not even with valgrind. This led me to trial and error. First I investigated if removing from Gemfile some gems with native compilation such as `pg` and `json` had any effect, but the error persisted after all my tries. After that I went to remove all gems and reinstall and the error persisted. Then I tried to remove the Ruby being used and reinstall it. Which fixed the problem! But I must admit this is an ugly solution. Now knowing the error source is within the Ruby installation, I've tried to upgrade the `zzet.rbenv` ansible galaxy module, but had no success. I've also tried to remove jemalloc from the installation and the error persisted. Finally I have moved the uninstall/reinstall to being the very next thing after calling `zzet.rbenv` and to my surprise it also fixed the problem! From this I can only conclude there is some unknown issue in this module that is beyond the scope of OFN. With this long description of what I have tried and failed I hope you understand that I've did my best to find a better solution, but had no success in my search. Uninstalling and reinstalling the same thing was the only solution that worked. Why it is a problem only in Ubuntu 20 and not 18 and 16 is another mystery. In the future, if someone accepts the quest of removing this ugly fix, the first thing I suggest to check is if there is a version of `zzet.rbenv` newer than 3.6.0 and, if there is such version, check if it fixes the error described here.

It is only necessary to run once per Ruby. Running it every time the provision playbook runs did not cause any error, but it took a while to run delaying deployments.
