scheduler: fix _get_sharing_providers to support unlimited aggr

Browse Source 
A Request-Too-Long error can be raised in case of too many aggregates
are attached to a host. The fix is to split the requests.

The request is executed by host via a periodic task. Result is set in
cache so no performances impact is expected.

The change introduce a new compute configuration option
`compute.sharing_providers_max_uuids_per_request = 200`.

Closes-bug: #2068893

Introduced a new compute configuration option
`sharing_providers_max_uuids_per_request` and applied a fix to
handle the "Request-Too-Long" error that can occur when querying
the placement API with a large number of aggregate UUIDs.
