total_count in the get artifacts api doesnot return the count of artifacts in all the realms even when the admin token is specified

[swathi]

get artifacts glare api with admin token returns all the artifacts in all the realm, whereas the total_count is still the number of artifacts in specific realm.

(get_all call in sqlalchemy/api.py takes "list_all_artifacts" flag, which indicates if the list should return list from all realms/specific realm. This flag is considered when fetching the artifacts, but is not considered when fetching the count of artifacts.

//Existing code in sqlalchemy/api.py:
artifacts = _get_all(
        context, session, filters, marker,
        limit, sort, latest, list_all_artifacts)
total_artifacts_count = get_artifact_count(context, session, filters,
                                               latest)

//Code with fix in sqlalchemy/api.py:
artifacts = _get_all(
        context, session, filters, marker,
        limit, sort, latest, list_all_artifacts)
total_artifacts_count = get_artifact_count(context, session, filters,
                                               latest, list_all_artifacts)
