[FEATURE] Isolate pipeline that performs unit tests and integration tests so that we get those insigts from PR before merge into main

**Is your feature request related to a problem? Please describe.**

Currently the pipelines are / were setup for deployment automation and do checks on the deployment. As the project has been opened up and we still want deployment to be behing the PR approval gate but we want at least the unit tests to run on PR.

**Describe the solution you'd like**

Run useful pipeline checks on the PR code before the merge in to main kicks off the deployment

**Describe alternatives you've considered**
