Enhance internal fetch functionality

[cdcabrera]

As a developer I need to expand the existing light fetch implementation to handle additional mime types and abort controller.

Acceptance criteria

• Expand fetch into its own file/resource

• Add abort controller setup

• Consider factory style, get, post, stop/cancel, status

• It MUST maintain its current integration into e2e testing.

Assumptions and questions

• Consider global state for applying a generic "abort controller" using asynclocalstorage context

• Prep for integrating into managed tasks associated with API crawling

• e2e testing in stdio mode means we have little insight into what's happening within the server beyond results and logging. our integrated fetch testing adds an additional insight into server behavior during stdio e2e testing
