Support environment configurations

This enables PDP-D to have knowledge of any installation
property or else configured via OS environment variable
or as an environment file.

This allows the user to query or set via REST API of programmatically
through PolicyEngine any environment variable.

It also provides a means to make data globally available to all
drools applications.

For example:

http://localhost:9696/policy/pdp/engine/environment> get

Content-Type: application/json
