 all of the alignment (and simplification) related with:
   - common interface at the PlatformAgent level  (removed all more specialized operations here; instead they went to the driver level)
   - moved specific functionality to the driver level, in fact, most of which now in RSNPlatformDriver, with some very basic and common driver functionality in the PlatformDriver class (mainly related with unconfig/disconn/connected states).
  - all "get" operations now via get_resource while all "execute" ones via
  execute_resource.
