Added custom environment variables to statsd

[RagingPuppies]

Hi,
This is not related to any issue, all airflow components have the option to add custom env to their docker container except statsd, I've just added the same functionality and tested the chart in debug mode. (as I don't think the unit tests have any relation to the helm charts.)

The chart does have unit tests as well!

Since this isn't an Airflow container, we don't need to use this helper here.

@jedcunningham as Flower is not an airflow container as well, but it did use the same code, don't you think it should be aligned?

airflow/chart/templates/flower/flower-deployment.yaml

Line 142 in 8f98bfe

{{- include "container_extra_envs" (list . .Values.flower.env) | indent 10 }}

[jedcunningham]

The difference is flower is started via the Airflow cli, and this run in a completely separate image that doesn't even have Airflow.

Are you still working on it @RagingPuppies ? If so - it needs rebase/conflict resolving

[RagingPuppies]

yes, @potiuk didn't have the time, pushed a new commit to fix @jedcunningham rejects.

Some conflicts still need to be solved @RagingPuppies now
