Refactor environment with Direct Persistence Layer

[ericpinet]

To improve the capability of the data structure of the environment, try to use the Direct Persistence Layer products to create a persistence set of objects in memory during the execution.

Products to try or look up:

• [x] Berkeley DB (DPL) (Not interesting)
• [x] Hibernate (Not interesting)
• [x] Neo4j (Trying that one)

I choose the Neo4j (Graph Database) to solve this issue. This is the todo list:

• [x] Adding DataManagerNeo4j
• [x] Disabled Cmd (to be revisited)
• [x] Remove or disabled UnitTest (to be revisited)
• [x] Remove FindProcessor mechanisims
• [x] Move to generateBaseEnvironment to DataManager
• [x] Adding DataManagerFactory to convert graph to data and json
• [x] Refactor Cmd (Environment)
• [x] Refactor ShellCmd
• [x] Refactor DeviceMngr
