Adds the test suite of algo and link FSM in the pipeline

This PR has been updated to run a git pipeline job for both plugins related to link and algo test suites. For the link test, I committed a config file and for algo test,
it uses config as in here: !31 (merged)

In addition, currently the --help option gives all the pytest related options as well in addition to custom-options of the code. The ability to print custom options only from pytest is still to be included within pytest itself as I understand. Once this feature is available, this will be taken care of.
