Catch and display concourse webhook errors

Catch errors in Subprocess.call to fly/concourse and display the error returned by concourse.

This is mainly for 404's on concourse pipelines/resources.

Check resource pull-request on push events not on master

Calls fly check-resource on pull-request resource on push events so we can run tests on pull requests for airflow dags and on lookup repositories

Fix: Set fly path to /home/app/bin/fly

Set fly executable path to /home/app/bin/fly as the docker container is run as USER app so needs write access to this path.

Update to use python-fly

Use python package python-fly to trigger resource checks instead of the concourse api

Bugfix for server shutdown

Check loop is open before waiting for pending tasks

small bugfix that prevents warnings when the server is stopped with a CTRL-C
signal, if the event loop is closed then there is no need to wait for pending
tasks.

First release 🚀

Webhook Dispatcher 0.1.0 Initial Commit

This is a webhook dispatcher for taking github org hooks and manually triggering
concourse pipelines.

This allows one github org hook to trigger all your pipelines instead of having
concourse poll your github org. The problem with polling is that it uses up all
of your github API request limit as the number of pipelines increases.
