CHANGE DESCRIPTION

Problem:
Add test fixes necessary for the release:

1. Add Storage Class that is expandable for EKS
2. Add Vault credentials to download Hashicorp Vault images from community repository
3. Align timeouts in gr-self-healing (720 seconds for cluster crash status) and remove whitespace from online members variable (reproduceble on EKS)
4. Crio is the default runtime when installing Chaos Mesh for Openshift, and containerd was default for tests on cloud (besides minikube)
5. Fix platform variable when installing Vault. Platform is used to determine the cloud provider, by default it was always kubernetes
