Clarifications to OpenStack gaps

I've made the following changes:
  - removed the direct references to Mitaka release, as this analyzis
might be updated to later releases.
  - Added the relevant OpenStack projects to the table
  - Made some clarifications to the existing gaps
  - Removed the "Is available in Mitaka" as none of them are avaiable ;)

+OpenRetriever Gap Analysis with OpenStack
+=========================================
+This section provides a gap analyzis between the targets of OpenRetriever for
+release Euphrates (E) or later and the features provided by OpenStack in release
+Ocata. As the OPNFV and OpenStack releases tend to change over time this
+analyzis is planned to be countinously updated.
+During the analyzis all OpenStack projects considered.
+
+(**Editors note:** Maybe we should define a scope of OpenStack projects which is
+considered. All OpenStack projects can mean anything.)
+
+The following table lists the use cases / feature requirements of container
+integrated functionality, and its gap analysis with OpenStack.
