Support find cache + gh action for core mlc actions

[anandhu-eng]

The changes proposed are to support mlc find cache command in MLC and to initiate the GitHub action for testing the core MLC actions.

After merging the PR, it may be observed that there are duplicate print statements of WARNING - No cache entry found for the specified tags! are being found when executing a script. Example is given below:

anandhu@anandhu-VivoBook-ASUSLaptop-X515UA-M515UA:~/Music/mlcflow$ python3 -m mlc.main run script --tags=get,imagenet-aux,_from.dropbox
/usr/lib/python3.10/runpy.py:126: RuntimeWarning: 'mlc.main' found in sys.modules after import of package 'mlc', but prior to execution of 'mlc.main'; this may result in unpredictable behaviour

This is due to the automation script in mlperf-automations repo calling the find action of MLC.

@arjunsuresh , would it be a good solution that we replace the calling of find action in mlperf-automation to search?

Its better to always use "--quiet" in the github actions as otherwise any prompt can fail the action.
