## Description This commit allows a tool to pull an alternate authorization token from the header of the http request. This is initially being built for the Looker integration. Looker uses its own OAuth token. When deploying MCP Toolbox to Cloud Run, the default token in the "Authorization" header is for authentication with Cloud Run. An alternate token can be put into another header by a client such as ADK or any other client that can programatically set http headers. This token will be used to authenticate with Looker. If needed, other sources can use this by setting the header name in the source config, passing it into the tool config, and returning the header name in the Tool GetAuthTokenHeaderName() function. ## PR Checklist > Thank you for opening a Pull Request!
