Support Mount Credentials

[falfaroc]

Description

With the recent changes to support the secret and config map, the processing within PowerMax Observability needed adjustment. This add the support for both approaches.

Also, we've stripped out duplication of a reverseproxy within here and leveraged the ability to import the Powermax Reverseproxy as a module to be used for parsing the secret/configmap.

The Code Coverage is 90% except for the mock packages.
