Authentication and Service Endpoint Retrieval; Addition of Environment Variable Defaults to Client Library

Authentication and service endpoint retrieval now works with the integration environment using both keep and the client library. Adding the variables defined in the newly added clientrc file to your environment allows for running the client on the integration environment without the need to provide any arguments.

I moved the function in keep that looked up environment variables to the client library, but keep still uses it to be able to display the default values in help messages.
