[HBase] get_resource optimization

In this change only Resource table is scanned during get_resources().

It becomes possible because of the following:
1. Store all meters for each resource.
2. QualifierFilter is used when timestamp filter is needed.
3. To make metadata up-to date in case of unusual order (old comes earlier then new)
   we use versioning. So during 'put' it's possible to set timestamp and the newest data will be
   automatically 'on the top'
