[PATCH proxmox v2 04/14] pbs-api-types: add flag to control usage statistics collection

[Christian Ebner <c.ebner@proxmox.com>]

Adds a flag to the datastore config in order to control when enabling
fine-grained hierarchy level usage statistics for namespaces, groups
and levels during garbage collection.

Defaults to false due to the additional memory requirements for
bookkeeping during garbage collection.
