This is the collection entry point. It accepts a manifest, a temporary
directory in which to store output, and a boolean for optional compression.
Args:
manifest (str or dict): json document or dictionary containing the
collection manifest. See default_manifest for an example.
tmp_path (str): The temporary directory that will be used to create a
working directory for storing component output as well as the final
tar.gz if one is generated.
compress (boolean): True to create a tar.gz and remove the original
workspace containing output. False to leave the workspace without
creating a tar.gz
rm_conf (dict): Client-provided python dict containing keys
"commands", "files", and "keywords", to be injected
into the manifest blacklist.
client_timeout (int): Client-provided command timeout value
Returns:
The full path to the created tar.gz or workspace.
