Add back support for -1 limits of child projects. The way that we
support the -1 child limits requires the following changes:
* Continue quota validation up the hierarchy if the current limit is
-1 until we hit a hard limit or no more parents, and update the
any relevant parents' allocated value along the way
* When updating limits, special care needs to be taken when updating
child limit to be -1, or when changing from a -1 limit
* Enable support for creating reservations for "allocated" values
to support the scenario that:
- a volume is created on a project with a limit of -1
- the parent's allocated value has been updated appropriately
- the volume create fails and the child's in_use quota rolls back
- now we must also rollback the parent's allocated value
NOTE: There is a race condition between validation the NestedQuotas
and when the driver may be switched into use, and if -1 quotas are used
the validation could be out of date. Will look into better support for
switching on of NestedQuotas on live deployment with -1 limits, which
would likely leverage the "allocated" reservation system.
