Deploy airflow multi-tenant env: one scheduler multiple nodes deployment

[r0ger]

We will have one pipeline per customer (1 DAG per customer). 

I am trying to think of how to build the entire workflow-setup with airflow.

We really dont want to introduce celery at this stage.

Specifically, I am trying to understand and implement the following:

1. How do I build my pipeline such that pipelines for certain set of customers go to Node1 while few go to node3 ...and so on.

2. Can I set up airflow such that there is one UI for all pipelines? 

If anyone has a similar set up, it will be worth discussing it here.
