- simplified branch and image tagging in CI
- minor cleanup of CI scripts

 - Add columns to tables workflow_requests and capability_requests
 - Make the updated_at column auto-update in the database for both
 - Use in the __repr__ method for Python for human-friendliness

Manually verified that the timezone manipulations were correct

 - REST API for Workflows is significantly revamped
 - REST API is now documented with Swagger
 - JSON Arguments to workflows and capabilities are now saved in Postgres properly

This reverts commit 68320db2.

Updated `testing/utils/conftest.py` with reliable mock data that can be used in tests; added `shared/workspaces` tests

WS-101: figured out how to write pytest tests. test_load_engine works, stubs for other tests created

existing executions cannot be deleted (they must be disabled instead,
which will have to be implemented)

and capability request)

Refactored execution management logic out of `CapabilityService` into a new class `ExecutionManager`

- Added PATH_PREFIX variable to build stage to handle dockerfiles at paths other than /services
- removed .unit-test template from .gitlab-ci.yml because it was duplicated

REST API gives out and parse that into the CapabilityRequest object

`CapabilityService.create_request` instead of duplicating that logic
within the view; changed tests and mocks to go along with the changes

fix CapabilityEngine to actually load the capability execution it's executing and then properly release the engine after completion
