Use supported version of fedora in CI (#10108) * tests: replace fedora35 with fedora37 Signed-off-by: Arthur Outhenin-Chalandre <arthur.outhenin-chalandre@proton.ch> * tests: replace fedora36 with fedora38 Signed-off-by: Arthur Outhenin-Chalandre <arthur.outhenin-chalandre@proton.ch> * docs: update fedora version in docs Signed-off-by: Arthur Outhenin-Chalandre <arthur.outhenin-chalandre@proton.ch> * molecule: upgrade fedora version Signed-off-by: Arthur Outhenin-Chalandre <arthur.outhenin-chalandre@proton.ch> * tests: upgrade fedora images for vagrant and kubevirt Signed-off-by: Arthur Outhenin-Chalandre <arthur.outhenin-chalandre@proton.ch> * vagrant: workaround to fix private network ip address in fedora Fedora stop supporting syconfig network script so we added a workaround here https://github.com/hashicorp/vagrant/issues/12762#issuecomment-1535957837 to fix it. * netowrkmanager: do not configure dns if using systemd-resolved We should not configure dns if we point to systemd-resolved. Systemd-resolved is using NetworkManager to infer the upstream DNS server so if we set NetworkManager to 127.0.0.53 it will prevent systemd-resolved to get the correct network DNS server.

Added file and container image caching (#4828) * File and container image downloads are now cached localy, so that repeated vagrant up/down runs do not trigger downloading of those files. This is especially useful on laptops with kubernetes runnig locally on vm's. The total size of the cache, after an ansible run, is currently around 800MB, so bandwidth (=time) savings can be quite significant. * When download_run_once is false, the default is still not to cache, but setting download_force_cache will still enable caching. * The local cache location can be set with download_cache_dir and defaults to /tmp/kubernetes_cache * A local docker instance is no longer required to cache docker images; Images are cached to file. A local docker instance is still required, though, if you wish to download images on localhost. * Fixed a FIXME, wher the argument was that delegate_to doesn't play nice with omit. That is a correct observation and the fix is to use default(inventory_host) instead of default(omit). See ansible/ansible#26009 * Removed "Register docker images info" task from download_container and set_docker_image_facts because it was faulty and unused. * Removed redundant when:download.{container,enabled,run_once} conditions from {sync,download}_container.yml * All features of commit d6fd0d2acaec9f53e75d82db30411f96a5bf2cc9 by Timoses <timosesu@gmail.com>, merged May 1st 2019, are included in this patch. Not all code was included verbatim, but each feature of that commit was checked to be working in this patch. One notable change: The actual downloading of the kubeadm images was moved to {download,sync)_container, to enable caching. Note 1: I considered splitting this patch, but most changes that are not directly related to caching, are a pleasant by-product of implementing the caching code, so splitting would be impractical. Note 2: I have my doubts about the usefulness of the upload, download and upgrade tags in the download role. Must they remain or can they be removed? If anybody knows, then please speak up.
