[In progress] CI Addition

[biswalc-roche]

Objectives:

• Implement continuous integration.
• CI to run on ubuntu-latest machines to prevent additional work for maintenance.
• Ci trigger based on branches.
• Since asset-manger is monorepo, build would be triggered based on paths.
• Only a single CI would run for the combination of ${{ github.workflow }}-${{ github.ref }}-${{ github.actor }} older build will be cancelled.
• Builds take couple of minutes at worst scenario, so timeout is set to 10 minutes.
• To start with, just Python 3.10 is supported in CI.
• Supports flake8
• Support pytest
• Upload to Github Artifactory as well as Pypi.org.
