Remove Extra Fields From Minimal CR

[anathoodell]

Description

This PR removes the extra fields from the CSM CR when deploying using a minimal sample. ensuring it is cleaner, more efficient, and thoroughly validated. Below is a summary of the changes:

Key Changes

1. Replica Count Fix

   • Adjusts the replica count in the CR to align with the correct controller counts.

2. Removal of Empty Fields

   • Eliminates empty structs such as csiDriver, Node, and Controller from the CR.

3. Environment Variable Cleanup

   • Removes the KUBELET_CONFIG_DIR field from the CR.

4. PowerFlex-Specific Changes

   • Removes initContainer and sdc-monitor fields for PowerFlex in the minimal configuration.

5. PowerMax-Specific Changes

   • Removes reverseproxy env variable fields for PowerMax in the minimal configuration.

6. Improved Unit Test Coverage

   • Increases UT coverage to 97%.

7. Fix Operator Crashing

   • Fix operator crashing when initContainer ENVs are empty
   • It will use secrets to update MDM

8. E2E Test Enhancements

   • Adds an E2E test step to the minimal standalone deployment to verify:
     • A non-zero replica count.
     • Absence of unexpected fields when using the minimal sample.

When installing powermax using minimal sample, we are adding the reverseproxy module to the CR:

csm-operator/pkg/drivers/powermax.go

Line 98 in d7827cb

if !foundRevProxy {

. Shouldn't we change this to update the yamls but not update the CSM spec (like we did for SDC init container for pflex) ?

Looks like this code handles the reverse proxy scenario well. Please see if additional UTs can be added. Please ensure operator E2E passes for all platforms (in pipeline nightly jobs) to ensure this does not affect anything adversely.
