[manual] Extend /api/v1/streams API endpoint.

Previously it only provided the list of all public streams; now it
allows one to specify any union of some of the following:
* all public streams
* all streams the user subscribed to

(the most relevant being the union of those two, which is what we want
for the "streams" page).

Or:
* all streams in realm (superuser only)

The manual task required is that when this is pushed to prod, we need
to also deploy the new sync-public-streams version to zmirror.
