As part of this PR, we should also have at least one of the example using RHCOS to ensure testing coverage for that OS

Sure @vburckhardt

[imprateeksh]

Added the default pool as RHCOS in multizone region example. Both RHEL 8 and RHCOS operating systems can be seen in two worker pools

Locally executed themultiple-mzr-cluster test. Here is the results output_test_1.txt This test has however failed but due to a different reason shown below, will again attempt to run the test.

Also, Failure is seen in PR tests as -

Two changes are in progress -

1. operating_system can be at two places in the code and validation is considered only at one place i.e. outside for default os but for worker pools map, now it is in progress.
2. Another validation to be added for this condition -

Scenarios, that I have verified in local are -

Sno	Scenario	Expected output	Actual output
1	If os is RHCOS then ocp version has to be >=4.15	No Error should be seen	Pass
2	If os is rhcos and ocp_version = 4.14	Error should be shown	Plan failed
3	If the default os is RHEL, worker pools' os also has to be RHEL	No Error should be seen	Pass
4	If the default os is RHEL and worker pools' os is RHCOS	Error should be shown	Fails, error is seen
I 5	If the default os is RHCOS and worker pools os is RHCOS	No error should be shown	Passed, no error is seen
6	If the default os is RHCOS and worker pools os is RHEL	No error should be shown	Passed, no error is seen

Some screenshots from the scenarios:

If the default os is RHEL, worker pools' os are also RHEL

If default os is RHCOS, worker pool os is RHEL

---

If default os is RHEL, worker pool os is RHCOS and also ocp_version provided is 4.14 ,

Error expected is seen:

---

Scenario 2 : If default os is RHCOS, worker pool os is RHEL and ocp_version provided is 4.14

Again error is expected and received as:

---

If default os is RHEL, worker pool os is RHCOS and ocp_version provided >= 4.15 ,
