[BP 7.1.4]: Buckets page should load even if the browser machine is slow or bandwidth is low

If the browser machine is slow or if bandwitdh is low it is possible that the buckets page won't load. What can happen is the following:

• UI attempts to read the bucket information from pools/default/buckets
• Response returns but due to the size of the payload it is possible that the UI will not receive the full payload before 4 s has elapsed
• The UI deems that the REST API isn't working cancels it and starts over.
• This cycle continues ad-infinitum and the buckets page doesn't load.

We should eventually present the buckets page even if the browser machine is slow or bandwidth is poor.
