Use streaming API for Application List UI view

[alexmt]

Summary

If Argo CD instance is managing 3k+ applications then API response might be more than 100mb. Without server side pagination API server might use a lot of memory and get OOM killed. API Server should support server-side pagination to handle 3k+ applications.

Proposal

Implement server-side pagination so that UI can load applications in chunks.

The decision is to leverage the existing application stream API to power the application page, and stop using the list API. This will allow apps to display much quicker.
