Ensure when use_oracle_public_repo is set to false the public Oracle Linux yum repos are not set (#7228)

Fixes the following error when using Bastion Node with the sample config.
```
fatal: [bastion]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'bastion'\n\nThe error appears to be in '/home/felix/inovex/kubespray/roles/bastion-ssh-config/tasks/main.yml': line 2, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n---\n- name: set bastion host IP\n  ^ here\n"}
```

Add retries to drain during upgrade. Allow leaving nodes cordoned after drain failure. Allow continuing upgrade if drain fails. (#7206)

* Allow configureable vni and port for flannel overlay

* additional options for azure cloud config

Previous check for presence of NM assumed "systemctl show
NetworkManager" would exit with a nonzero status code, which seems not
the case anymore with recent Flatcar Container Linux.

This new check also checks the activeness of network manager, as
`is-active` implies presence.

This was introduced in 143e2272
Extra repo is enabled by default in CentOS, and is not the right repo for EL8
Instead of adding a CentOS repo to RHEL, enable the needed RHEL repos with rhsm_repository

For RHEL 7, we need the "extras" repo for container-selinux
For RHEL 8, we need the "appstream" repo for container-selinux, ipvsadm and socat

Implemented in #6547

Only checking the kubernetes api on the first master when upgrading is not enough.
Each master needs to be checked before it's upgrade.

yum_repository expect really different params, so nothing to factor here
Ubuntu is not an ansible_os_family, the OS family for Ubuntu is Debian
Check for ansible_pkg_mgr == apt

Here the desciption from Ansible docs
Corresponds to the --force-yes to apt-get and implies allow_unauthenticated: yes
This option will disable checking both the packages' signatures and the certificates of the web servers they are downloaded from.
This option *is not* the equivalent of passing the -f flag to apt-get on the command line
**This is a destructive operation with the potential to destroy your system, and it should almost never be used.** Please also see man apt-get for more information.
