Description of contribution in a few bullet points

• Added a delete command for vcs to remove all the paths specified under the YAML repository file.
• By default, the following command prints information about the YAML file, but does not delete until a -f/--force option is passed:

  $ vcs delete --input list.repos .
  Warning: The following paths do not exist:
    ./immutable/hash
    ./immutable/hash_tar
    ./immutable/hash_zip
    ./immutable/tag
    ./without_version
  The following paths will be deleted:
    ./vcs2l
  Dry-run mode: No directories were deleted. Use -f/--force to actually delete them.

• Updated the testing framework to account for various edge cases regarding the delete feature.
• Updated the README to include information on how to use the new command.

Description of how this change was tested

• Ran pytest locally to ensure all the unit and linting tests pass:

  pytest -s -v test

• Created a local fork to validate green CI.

Left some nitpicks in terms of unifying naming towards directories or paths when given messages to the user.
Overall I think it looks good to me.
I think we should add a test-guard that checks that only the folders specified in the yaml are being deleted since users might have other stuff co-living with repositories managed by vcs.

What would happen if the YAML is empty?

[leander-dsouza]

You would get the following error:

Error: Failed to read repositories: Input data is not valid format: 'NoneType' object is not subscriptable

This is captured from the following line in delete.py.

I have added a few assertions in the integration test to verify the specific deletion of folders over here.
