Investigate options for E2E testing of logging to the sandbox cluster

[odockal]

Automate the real scenario for logging into RH account either using SSO or RH Account via browser is not an easy task.

We need to explore other option how to gain OS cluster login token:

• crc microshift
• crc openshift preset
• setup sso and cluster locally or as a service
• use existing options for testing - internal or external
