Cinder count api
There is no current API that can retrieve summary count data for volumes and search filters. For example, getting the total number of volumes that match a given filter criteria (for example, all volumes in a given state). Retrieving all volumes and then manually determining the count data does not scale.
A UI dashboard that contains volumes in various states. A new API is needed to retrieve the volume count data associated with various filters (ie, volumes in available state, volumes in error state, etc.)
