WS-239 problem: argparse is not behaving as advertised; should auto-generate help, but throws SystemExit(0)

- aat_wrest: utility for pulling metadata for calibration templates
- wf_framework: contains script for setting up CASA processing directory structure

WS-239 and WS-184: failing tests are disabled pending rewrite, AND passing around of namespaces is eliminated. It would've been difficult to do in two pieces.

removed EXPOSE cmd in frontend's Dockerfile.dev and added empty dependencies to CI stages that don't need artifacts for efficiency

Added stubbed front-end support for calibration (the button prints to the console when clicked instead of launching a capability normally)

This reverts commit 48361c15.

- Capability request status page now grabs all correct information from its request and fills that into the UI
- If the request is complete and the execution has a delivery URL, a download button appears on the page linking to the download area

help

* args are accessed only in locations_report.__init()__
* directory/file-related errors throw custom exception

- Two new `npm` packages (not including deps): `eslint` (linter for TypeScript code) and `prettier` (multi-language web-stack code formatter)
- New workspaces component: `capability-request` which is where the work for the page is being done

WS-195, WS-76: Notification System now working and sending emails on request submission and completion

 - New DestinationTempFile for writing tempfiles into the destination which eventually get added
 - All of the close() methods are now streaming
 - Implemented ChecksumDecorator
 - Implemented FetchFile decorator
