Joseph Yen created AIRFLOW-1356:
-----------------------------------

             Summary: add celery hostname option `--celery_hostname` to CLI command `airflow worker`
                 Key: AIRFLOW-1356
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1356
             Project: Apache Airflow
          Issue Type: Improvement
          Components: celery, cli
    Affects Versions: 1.8.1
            Reporter: Joseph Yen
            Priority: Minor


If we start multiple `celery worker` on the same machine, each worker should have individual hostname to distinguish each other. Otherwise, some tools might not work correctly. E.g. celery flower would show only one worker if they all set the same hostname.

It's necessary to have `--celery_hostname` option on `airflow worker` subcommand, and the option should accept an argument with the syntax as same as the option `-n` of `celery worker` command.
