K8SPSMDB add support for Rancher

[valmiranogueira]

CHANGE DESCRIPTION

Solution:

Fixes and improvements for Rancher tests

• Fixed volume expansion validation: there is a difference between G and Gi units. 1G is converted to approximately 954Mi, which can cause issues with storage providers that enforce strict capacity calculations, such as Longhorn (https://longhorn.io/).
• Improved monitoring support functions to properly handle generated passwords containing the @ character. Since this character is not URL-safe, it was causing intermittent test failures. In addition to that, created execute_curl function to run the request within the cluster to avoid intermittent requests
• Refactored container runtime detection logic into a generic function and standardized the runtime class to runc. This improves compatibility with platforms such as EKS and Rancher, where Docker is no longer supported.
• Enhanced PLATFORM variable support. The variable is now exported and supports predefined values such as EKS, AKS, RANCHER, MINIKUBE...

Additional changes

• Removed obsolete comparison files related to OpenShift versions earlier than 4.x.
• Added a dedicated variables file to centralize configuration and remove variable definitions from function scripts.
• Removed function file imports during image build. Some imported files contained kubectl function calls executed during variable initialization, which are unnecessary during the build process.

CHECKLIST

Jira

• Is the Jira ticket created and referenced properly?
• Does the Jira ticket have the proper statuses for documentation (Needs Doc) and QA (Needs QA)?
• Does the Jira ticket link to the proper milestone (Fix Version field)?

Tests

• Is an E2E test/test case added for the new feature/change?
• Are unit tests added where appropriate?
• Are OpenShift compare files changed for E2E tests (compare/*-oc.yml)?

Config/Logging/Testability

• Are all needed new/changed options added to default YAML files?
• Are all needed new/changed options added to the Helm Chart?
• Did we add proper logging messages for operator actions?
• Did we ensure compatibility with the previous version or cluster upgrade process?
• Does the change support oldest and newest supported MongoDB version?
• Does the change support oldest and newest supported Kubernetes version?

Pull request overview

This PR updates the E2E test harness to run reliably on Rancher/RKE2 (and other managed Kubernetes platforms) by centralizing test configuration, normalizing storage sizing, and refactoring runtime-class / monitoring / snapshot helpers to be platform-aware.

Changes:

• Centralized E2E environment variables and platform detection into e2e-tests/vars and refactored e2e-tests/functions to source it.
• Normalized PVC resize/storage requests from G to Gi across resize/autoscaling tests to avoid provider-specific rounding issues (e.g., Longhorn).
• Added Rancher-specific snapshot class support and hardened PMM/monitoring interactions by routing curl calls through a helper (to better handle special characters in credentials).
