initial shotgrid client

[shhlife]

Created an initial Shotgrid client to work with Autodesk Shotgrid.

For this to work, you'll need a Shotgrid account. Once you have that, you'll need:
site: The URL of your Shotgrid server
script_name: The name of the API script registered in Shotgrid.
script_key: API key of the script registered in shotgrid.

Information on how to create the script and API keys:

Here's how you would define an agent once you have those:

# Set the variables
SERVER_PATH = "https://my-shotgrid-url.shotgrid.autodesk.com"
SCRIPT_NAME = "myscript"
SCRIPT_KEY = "xxxx-xxxxxxxxxxxxxxx"

# Define the agent
agent = Agent(
  tools=[
    ShotgridClient(
      site=SERVER_PATH, 
      script_name=SCRIPT_NAME, 
      script_key=SCRIPT_KEY)
  ]
)
