[AIRFLOW-4265] Lineage backend did not work normally (#5067)
* add debug log
* change SendMessage to staticmethod
* updated doc
> Lineage backend did not work normally
> -------------------------------------
>
> Key: AIRFLOW-4265
> URL: https://issues.apache.org/jira/browse/AIRFLOW-4265
> Project: Apache Airflow
> Issue Type: Bug
> Reporter: Bryan Yang
> Assignee: Bryan Yang
> Priority: Major
>
> 1. Lineage backend comes from {{import_string}} function, and
> {{import_string}} will try to seperate module_path and class_name by dot.
> {quote}def import_string(dotted_path):
> """
> Import a dotted module path and return the attribute/class designated by the
> last name in the path. Raise ImportError if the import failed.
> """
> try:
> module_path, class_name = dotted_path.rsplit('.', 1)
> except ValueError:
> raise ImportError("{} doesn't look like a module path".format(dotted_path))
> module = import_module(module_path)
> {quote}
> But in the current document: {{backend = airflow.lineage.backend.atlas}}
> which is just a module path without class name \{{AtlasBackend}}.
> 2. Continuously, this function will return a module or class instead of an
> instance. So that when {{apply_lineage}} want to call
> {{backend.send_lineage}}, it will fail.
