Refresh Airflow UI

[turbaszek]

Description

As the Airflow 2.0 is coming nearer it would be awesome to refresh the Airflow WebUI. By this it mostly means:

• using some "modern colors" (how about Airflow logo palette?)
• fixing some padding/spacing
• and other small HTML / CSS touches

Use case / motivation

The main point is to refresh the look, not to rewrite the Web UI.

Yes, I'm definitely interested in taking this on—I've got a few ideas brewing.
