             Summary: design and implement configuration interface for stand-alone Stellar
                 Key: METRON-989
                 URL: https://issues.apache.org/jira/browse/METRON-989
             Project: Metron
          Issue Type: Sub-task
            Reporter: Matt Foley


In the first effort to separate Stellar from Metron, I left a truncated version of Metron's configuration model in Stellar.  This isn't very satisfactory.  The goals should be:
# User must be able to configure Stellar itself, regardless of the platform it is plugged into.
# Stellar's configuration model should not be grossly Metron-specific; ideally it should be storage-agnostic and possibly schema-driven.
# We would like to still be able to use Stellar to manipulate the Metron-specific config when plugged into Metron.  Reading and setting are required, since Stellar has become a major tool of convenience for managing Metron's config.
# We would like to be able to use Stellar to manipulate the application-specific config of other platforms when Stellar is plugged into them, if the other platform allows.  Reading is more important than setting.

The last two items argue for a client interface layer where the platform can provision Stellar's config model as the platform prefers.

Investigate whether Apache commons configuration would be appropriate, perhaps with add-ins for JSON sources and Curator event support.
