CPS-505: Get and Store SchemaSets of node(s) in initial Inventory (new modules only)

CPS-505 - Getting issue details... STATUS

Background

When a new CM handle is encountered by the DMI plugin, NCMP is notified via REST. Once NCMP picks up the new CM handle it needs to determine what modules exist for it in the database and figure out which modules are missing. DMI plugin is contacted for all modules for this new node and they are matched to what CPS has. Missing modules are then retrieved from DMI and entered into the database.

High Level Proposal of Work to be done

1. Call dmi–plugin rest endpoint to retrieve all modules on new node (depends CPS-483 and CPS-531)
2. Call CPS-Core rest endpoint to get all existing modules in cps-core (depends CPS-506)
3. Calculate difference (delta) 
4. Call dmi–plugin rest endpoint to retrieve missing modules CPS-483
5. Add missing modules to cps-core to anchor (cm handle) (depends CPS-508)
