Updates the image building to Airflow 1.10, including necessary
configuration changes and a general update of dependencies.
Airflow 1.10 includes many enhancements and bugfixes since 1.9 [0]
This change introduces many "unused" configuration parameters to satsify
Airflow's expectations[1]. An ugly, but likely harmless change to the
log output with interleaved newline characters from Airflow steps[2].
Changes to the chart and other dependendencies have also been introduced
to match this update.
