Represents the leaf level constraint to restrict the number instances of type.
Represents the leaf level constraint to restrict the number of instances of an entity
type that can be created.
Lowering the limit on the number of instances of a given type is allowed even in cases
where there are instances more than the specified limit already in the system.
In this case, creation of new instances of that type will be disallowed unless the number
of instances goes below the limit.
One of the main usage of this expression is to implement Quotas in the multi-tenancy context.
It allows to limit the number of resources which can be created inside a Project.
It also allows to forbid consumption of specific resource by putting its entity count to 0.
Note that, update/delete operations will continue to be allowed on already created instances.

| _protection | Indicates protection status of this resource Protection status is one of the following: PROTECTED - the client who retrieved the entity is not allowed to modify it. NOT_PROTECTED - the client who retrieved the entity is allowed to modify it REQUIRE_OVERRIDE - the client who retrieved the entity is a super user and can modify it, but only when providing the request header X-Allow-Overwrite=true.

| _revision | Generation of this resource config The _revision property describes the current revision of the resource. To prevent clients from overwriting each other's changes, PUT operations must include the current _revision of the resource, which clients should obtain by issuing a GET operation. If the _revision provided in a PUT request is missing or stale, the operation will be rejected. |
