AggregateMultitenancyIsolation to support unlimited tenant

Registered by Sahid Orentino

This blueprint proposes an enhancement to the AggregateMultitenancyIsolation scheduler filter, specifically removing the previous limitation on the number of tenants that can be filtered using the filter_tenant_id aggregate property.
Rationale

The existing limitation on the number of tenants that can be filtered using the filter_tenant_id property is too restrictive for environments with a large number of tenants. This update aims to make this feature more flexible and scalable.

Changes

    The filter_tenant_id can now be used as a suffix, allowing to accept an unlimited number of tenant IDs.

Backward Compatibility

    The update will maintain backward compatibility, allowing the existing configurations to function as they currently do.
