Build a color extractor in AWS Lambda

[vishnugopal]

Discussion:

• Most of the serverless framework issues have been solved.
• AWS permission issues are also been sorted for a normal deploy.
• Converted the url-analyzer to typescript, and have similar ways to test locally. Trying to keep it similar to the color extractor.
• Let's wait until we integrate into the tool in MC.
• For local development, let's run everything inside a container.
• Let's talk to Alex to figure out how to deploy this for site-parser credentials.
