Description

This PR removes injection of CSM Authorization from the installer script and now enables CSM Authorization if the following conditions are met:

• The proxy-authz-tokens, karavi-authorization-config, and proxy-server-root-certificate Secrets exist in the CSI PowerFlex driver namespace
• The vxflexos-config-params ConfigMap exists in the CSI PowerFlex driver namespace

How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Please also list any relevant details for your test configuration

• Ran the script to "install" CSM Observability in two different environments, 1) The CSI PowerFlex driver was already installed with CSM Authorization enabled 2) The CSI PowerFlex driver was already installed with CSM Authorization disabled. The script will enable Authorization only if the necessary secrets are in the driver namespace
• Ran the script to "upgrade" CSM Observability with CSM Authorization enabled
• Ran the script to "enable-authorization" in an environment where Authorization was not initially enabled when installing CSI PowerFlex and deploying CSM Observability, but the driver was later upgraded to enable Authorization.
