Removed lots of v1 APIs... we are cruising to V2.

@rajthilakmca @morpheyesh @thomasalrin  Please read through the upcoming API changes.  This causes our current `nilavu` useless  :8ball: 

@thomasalrin  This means you need to bring nilavu up with the new UX/UI and the cookbooks tested on monday.

Nuked the following api's, its associated model, json serializer.

     Name|  Why
------------|-----------------------------------------
`Nodes` | replaced by modern powerful assemblies`
`CloudTools` | `command is no longer needed, its built in megamd now`
`AppDefns` | `no longer needed as its handled by components`
`BoltDefns` | `no longer needed as its handled by components`
`AppReqs` | `There will be no differentiation for app + db reqs just one requests should be good.`
`BoltReqs` | `There will be no differentiation for app + db reqs just one requests should be good.`
`Logs` | `Dead code that was there covering a commandline scenario.` 

- `megam_common` upgraded to `0.5.7` which is built on top of `basho-riak-java`  `2.0.0`.

- PlatformAppPrimer will not initialize `CloudTools` and no longer needed in `0.5`. This was just used for building a command, which is no longer the case in `0.5`. @rajthilakmca  Excellent effort buddy. Keep it up.
