NSFS | NC | Use --from_file Option in Bucket Create

[shirady]

Explain the changes

1. Add the from_file option in the bucket that would include validation. The JSON file will include options (as key-value structure) that are the same as the flags we suggest.
2. Add a special case of bucket_policy as an object in the JSON file.
3. Edit documentation of from_file with an example of bucket creation in addition to account creation.
4. Edit comments in file test_nc_nsfs_account_cli.test.js of typo (‘tha’ instead of ‘the’) and remove the ‘and check the details’ in case the tests should fail.
5. In Add bucket tests to file test_nc_nsfs_bucket_cli.test.js:

• Add bucket tests using from_file option, and copy functions from the account test file.
• Edit the tests not to have a global variable of bucket_storage_path, and bucket_temp_dir_path but local in the describe scope (else it creates issues since Jest running the tests in concurrency)

Issues:

Currently, we had a gap in from_file when adding a new bucket.

Testing Instructions:

Added unit tests, please run: sudo npx jest test_nc_nsfs_bucket_cli.test.js
