    [LIBCLOUD-996] Support GCP service_account authentication from JSON obj/str

    ## Support GCP service_account authentication from JSON obj/str
    
    ### Description
    
    
    Currently GCP service_account authentication credentials can be provided using the JSON/PEM file acquired from GCP console or gcloud utility. It would be convenient if the JSON content could be directly provided as an object or serialized JSON string to eliminate the need of having the file locally on the calling host.
    
    In this PR:
    - add logic to support JSON dict and str handling
    - rearrange PEM/JSON related GCE_PARAMS_* constant names in test_google.py for better clarity
    - add tests for JSON content as a dict and as a str
    
    
    ### Status
    
    - done, ready for review
