While working on https://github.com/certbot/certbot/issues/8400, I noticed our Fedora AMIs are quite out of date. I considered updating them and what we could do to avoid the AMIs becoming so out-of-date in the future, but I think we don't actually need these tests.
I pulled a new count of Certbot users by OS and we have less than 7,000 Fedora users meaning only ~0.26% of Certbot users run Fedora. (I think Fedora is a popular desktop OS, but not as popular of a server OS which is where Certbot normally runs.)
Also, Certbot is regularly updated on Fedora including Fedora Rawhide or the rolling release version of Fedora which is similar to Debian sid/unstable. Rawhide changes far too frequently for it to make sense for us to run tests there in my opinon, but that also means that many problems such as Certbot's unit tests failing to run because of Fedora changes will be caught there by our Fedora maintainers before we'd even see it. This is how https://github.com/certbot/certbot/issues/7106 became an issue and how I learned [Certbot worked on Python 3.9 before we could run tests on it](https://github.com/certbot/certbot/issues/8134#issuecomment-655106169).
Because of all this, I think we should just simplify things and remove these tests. If a problem arises in the future, we can always add them back.
* Create bootstrap script
* Delete a whole bunch of the bootstrap script
* modify test_tests to use new script
* put python version checking in back in
* add x
* call the venv creation from inside the bootstrap
* add targets back
* modify test_apache2 to use new format
* shouldn't need virtualenv on rhel
* readd targets
* Update test_sdists to use new script
* move setting up venv back out of script so it's not run with sudo
* take venv3.py call out of bootstrap in all scripts
* add additional python3-devel pkg name
* fix test_sdists
* enable additional rhel7 repos
* clean up code and comments
* Update tests and instructions to use auto_targets.yaml with test_leauto_upgrades.sh and test_letsencrypt_auto_certonly_standalone.sh
* only install python3-devel.x86_64 for rhel7
* Upgrade python version for debian in test_apache2.sh
* don't run test_tests or test_sdists on debian 9 or ubuntu 16.04
* Add 20.04 and 20.04 arm images to targets.yaml
* use pyenv to upgrade to python3.5
* remove arm64 instance because it's having auth trouble
* correct pyenv usage on ubuntu
* add arm64 target to targets.yaml
* replace debian 9 arm64 with ubuntu 20
* don't try to upgrade a perfectly good python version
* let's just add ubuntu20 to apache2_targets while we're here
* uncomment test_apache2
* move adding python3-devel.x86_64 to bootstrap_os_packages to avoid potential race condition
* no need to specify the arch once extra rhel7 repos enabled
* explicitly specify python3
* don't fail if we can't enable rhel7 extras
* capture python36-devel as well
