https://github.com/apache/airflow/pull/46613 introduced a machinery for
operator links to be used via xcoms and task sdk by introducing a new class
`XComOperatorLink` and https://github.com/apache/airflow/pull/47008 moved it to
the task sdk. Now that I think about it, it should not reside in the task sdk
because it is only used by the DAG processor while serialising / deserialising
that too while actually running it (api servrer)
Moving it to serialised_objects instead, where its used.
Plugin present:
Plugin used:
```
from airflow.plugins_manager import AirflowPlugin
from airflow.sdk.definitions.baseoperatorlink import BaseOperatorLink
from airflow.providers.standard.operators.python import PythonOperator
# define the extra link
class HTTPDocsLink(BaseOperatorLink):
# name the link button in the UI
name = "HTTP docs"
# add the button to one or more operators
operators = [PythonOperator]
# provide the link
def get_link(self, operator, *, ti_key=None):
return "https://developer.mozilla.org/en-US/docs/Web/HTTP";
# define the plugin class
class AirflowExtraLinkPlugin(AirflowPlugin):
name = "extra_link_plugin"
operator_extra_links = [
HTTPDocsLink(),
]
