Epic Goal

To be described better in future edits:

• Make use of get-subscriptions API's "fields" parameter to trim the returned results to the ones we need.  (Don't send unnecessary bytes over the network.)
• Do more server-side (RHOCM service) side filtering by extending the use of the API's "search" capability to include the things we're filtering out on the client side (eg. filtering out by Archived etc. status, missing external_cluser_id, etc.).
• Increase page size to maybe 1000 entries so there are fewer round trips per query (at the cost of some more memory in the controller, of course).  Reducing round trips will speed things up since it reduces the total network latency component of a query cycle.

Why is this important?

• Reduce the overhead of each polling/query cycle makes it more practical to enable discovery in envs with lots of clusters in the customer's RH org.
• Would allow us to increase polling frequency to achieve more responsive updates.
