Commit 0a5fb7856b545073516210fcfc369d2072823ae9 in incubator-airflow's branch refs/heads/v1-8-test

[AIRFLOW-1004][AIRFLOW-276] Fix `airflow webserver -D` to run in background

AIRFLOW-276 introduced a monitor process for gunicorn
to find new files in the dag folder, but it also changed
`airflow webserver -D`'s behavior to run in foreground.
This PR fixes that by running the monitor as a daemon
process.

Closes #2208 from sekikn/AIRFLOW-1004

(cherry picked from commit a9b20a04b052e9479dbb79fd46124293085610e9)
