Public bug reported:

The require_tenant_aggregate request filter was added in
Idb52b2a9af539df653da7a36763cb9a1d0de3d1b, it queries
hosts aggregates by its metadata, and since it is used
for matching spesific "filter_tenant_id:123" key and value
pairs. As the host aggregates table only has index
for metadata key, it is possible that with a large number
of tenants, the performance could be bad. We should also
add value to the index.
