Other styles and utils changes to support the new DAG editor

Description

Part 6 of the set of changes implementing the new DAG editor for CDAP UI.

Links to the previous changesets:

1. [feature/new-dag-editor] part 1: Add changes to the dag-plus directive #1309
2. [feature/new-dag-editor] part 2: Add back the older my-dag-ctrl to keep supporting the older ui #1312
3. [feature/new-dag-editor] part 3: update build configs and add reactflow as dependency #1313
4. [feature/new-dag-editor] part 4: Add the main component for the reactflow based DAG editor #1316
5. [feature/new-dag-editor] part 5: Add components for the DAG Nodes and Edges #1317

In this PR, we add some minor css and utility changes to make the new DAG editor render correctly. We also add the capability to remove the footer from any page (though additional css changes may be required in case of some pages with rigid layouts).

This PR will be followed by one last part with fixes and updates for broken testcases.
