SSA-6803: removed obsolete/possibly-not-needed scripts. Updated project root (data => workspaces) and now tests that passed before still pass.

system since I figure that's on its way out the door)

SSA-6383: Eliminated duplicate test data from copies in datafetcher/; fixed tests that broke as a result; addressed pylint & SonarLint issues

SSA-6324: proof of concept -- running tests in Docker container. These tests all pass at the pytest command line -AND- inside a  container. scode project updater code removed -- doesn't work, and will be merged in from archive eventually.

Changed import statements to break local testing but fix automatic conda build testing. I'm not sure how to resolve the different import needs.

SSA-6324: refactored prop setter for testability and created tests; added script to run all tests in data repo

SSA-6324: tests pass when run locally; some fail in Docker container. Committing what I've got so as not to lose it after tearing my hair out for a day and a half.

SSA-6324: placate Pylint somewhat; this time -really- get rid of the properties file after the Docker image is built; look what Pathlib can do!

SSA-6324: pytest on datafetcher_test.py executes in a Docker container. capo properties file is copied to the docker build directory, then deleted.

Tests all succeed when executed in IJ.

SSA-6325: a few import and path tweaks were necessary to get all the tests to run from the command line

master: reorganized datafetcher "SDM-only" functionality removed. All tests pass, including those that launch DF from a process to simulate command-line execution. TODO: actual command line, as below, should work but doesn't yet:

datafetcher --profile local --output-dir ~/Downloads --product-locator uid://evla/execblock/93e1c0cd-76de-4e65-a3f2-d5fe55f386d8 --verbose

Pylint also finds some errors, the consequence of fixing which puts red ink in the IJ editor and causes the above-mentioned command-line tests to fail.
