Multi-tenancy isolation with aggregates
A new scheduler filter that allows the creation of instances from
specific tenants in selected aggregates.
With this filter is possible to isolate tenants in a specific set
of compute nodes (aggregates).
If a host is in an aggregate that has the metadata key
"filter_tenant_id" it can only create instances from that tenant(s).
A host can be in different aggregates.
If a host doesn't belong to an aggregate with the metadata key
"filter_tenant_id" it can create instances from all tenants.
Implements: blueprint multi-tenancy-aggregates
