Update Docker build to remove dependency on build script

[tdawe]

Description

Updates build process for the CSI PowerMax driver and Reverse Proxy with following changes. This follows build processes for other drivers and modules:

• Remove hardcoded golang version dependency from the reverse-proxy image build
• Remove requirement to have all of the go libraries downloaded separately
• Remove build.sh file and use common configuration
• Build the reverse-proxy image as part of the docker targets for building the CSI driver
• Set defaults using overrides.mk and docker.mk files

@tdawe As an optimization, is it possible that we don't delete packages immediately after deletion and use it. Ex. driver builds first and downloads 73 packages, and once its done they are removed. reverse-proxy builds next and it also downloads 73 packages, was thinking if we can avoid remove after driver build, then we dont need to pull again. Just a thought.
