Merge unit and integ tests (#8805)

* Merge unit & integration testing build steps
* Remove '@Intregation' and '@ExtendedUnitTest' tags, run integ tests with unit

- Also cleanup upload of codacy coverage reports. We were doing
so conditionally and were not due to lack of token being defined.

* Add start-database to 'verify' script, now that DB is needed for unit tests

* Delete smoke-testing:integTest task, now incorporated in smoke-testing:test task

* Add postgres config to run-unit-tests workflow file
