[UI] list view performance improvements

[jessesuen]

Is this a BUG REPORT or FEATURE REQUEST?: FEATURE REQUEST

What happened:

Argo UI currently returns the entire payload of each workflow in the list view. However this can be dozens of megabytes in size. The UI only needs a few fields in the list view (e.g. phase, name, namespace, timestamps, etc...). We can improve the UI server to drop most of the fields (namely status.nodes) so that the payload of the list view is much smaller, and the performance would be improved.

Here is an example of where the list view is a problem because of payload size:

Environment:

• Argo version: v2.2.0
