Remove redundant copy of the load_labels_file method (#1901)

* Removes `morpheus.cli.utils.load_labels_file` in favor of `morpheus.utils.file_utils.load_labels_file` since this method is of use outside of the CLI tools.
* For backwards compatibility `load_labels_file` is imported into `morpheus.cli.utils`
