* Add oraclelinux8 and disable firewalld

Add oraclelinux8 image and disable firewalld on oraclelinux VMs

* Fix Oracle Linux repositories

As documented in: http://yum.oracle.com/getting-started.html#installing-software-from-oracle-linux-yum-server
public-yum-ol7.repo was deprecated on release 7.6. Some repos were integrated into oracle-linux-ol7.repo (i.e.: ol7_latest, ol7_addons) and other are available as packages (epel). This also adds support for oraclelinux8

* Fix to use ansible_distribution_version

Instead of ansible_distribution_major_version

* Update README.md

* bump csi containers

* bump snapshoter to 2.1.1

On OpenStack history, we used to call "tenant" for separeted namespace.
However we use "project" now instead.
Then we have replaced "tenant" with "project". Then all "TENANT" variables
also are renamed to "PROJECT".
This makes Kubespray search "PROJECT" variable also for newer OpenStack
clouds.

... to have working `hostPort` for containers.

flannel, ovn and multus network plugins did not support all taint keys. This
update changes the tolerations to support them all.

According to the documentation:

```
There are two special cases: An empty key with operator Exists matches all keys,
values and effects which means this will tolerate everything. An empty effect matches
all effects with key key.
```

Usage of the empty `key` and `effect` ensures the network plugin daemonset will
be deployed on every nodes (ex: in case of custom taints, or NoExecute effect)

disable bird-check flag for probes of calico-node pods when calico_network_backend is not 'bird'. (#6217)

* Update containerd package to 1.2.13-3.2.el7

* Update Fedora containerd package versions.

* Update Redhat containerd stable and edge packages.

Modify the populate no_proxy task to use a combine rather than relying on the hash_behaviour setting to be set to merge rather than replace (#6112)

Since weave 2.5.1, `NoExecute` taint effect is no more supported,
this changes the daemonset tolerations to change this behavior.

Also remove the toleration key `CriticalAddonsOnly` not required anymore.
