Dev/mip 14/config files restructure

Created by: ThanKarab

Following the MIP-14 ticket the following changes were made:

1. Decoupled the node_catalog and the node config file variables.
2. Split the mipengine config files into one per service (controller, node).
3. Node config file location can now be provided as env variable.
4. Deployment scripts were changed to deploy the services with the env variable config file logic.
5. The Node is now providing it's data to the node_catalog. The node_catalog does NOT need to be manually altered.
