Quota driver "DbQuotaNoLockDriver" should implement "get_detailed_project_quotas"

[Rodolfo Alonso]

Checking the logs, when the quota details are requested and "DbQuotaNoLockDriver" is loaded, some resources usages are "recalculated". E.g.:
  Quota usage for security_group_rule was recalculated. Used quota:13. count_used

The driver "DbQuotaNoLockDriver" does not use the database table "quotausages"; instead of this, the new method "DbQuotaNoLockDriver.get_detailed_project_quotas" should count directly from the database the resource count.

    Implement specific tracked resource count method per quota driver

    This patch implements a new method specific for each quota driver
    class. This method, "get_resource_count", returns the current number
    of resources created in a project of a tracked resource. A tracked
    resource is an instance of ``neutron.quota.resource.TrackedResource``.
    This method does not count the current reservations, just the actual
    resources created.

    This new method, "get_resource_count", will be added to the abstract
    class ``neutron_lib.db.quota_api.QuotaDriverAPI``.

    This patch also fixes ``TestDbQuotaDriverNoLock``, that was using a
    plugin inheriting from ``DbQuotaDriver`` instead of
    ``DbQuotaNoLockDriver``.

    Closes-Bug: #1982962
