Go ScaleIO Client Refresh

[vladimirvivien]

The Go ScaleIO client code (goscaleio) is a crucial part of several of {code}'s open source projects including the Kubernetes ScaleIO volume plugin. In the future, it will continue to be integral in creating new tools for ScaleIO and CSI. This issue is to track a revamp of the goscaleio codebase to accomplish the followings:

• Update, where possible, for consistency
• Aggregate http connection code to a single function
• Simplify API type hierarchy
• Attach all api operations to the Client type to reduce type sprawl
• Increase test coverage by adding tests for all major operations
• Maintain old API type structure for backward compatibility

Trackable steps to getting this done

• Rebase work on branch - https://github.com/vladimirvivien/goscaleio/tree/feature/code-refresh
• Merge latest changes from upstream
• Ensure items above are implemented
• Regression tests with libStorage plugins
• Regression tests with Kubernetes Volume Plugin
