            Description

            One of the key comment from the discussions was to modularize the SPS code, so we can easily plug in the external/internal implementations. This JIRA for doing the necessary refactoring.

            So other comments to handle
            Daryn:

            1. Lock should not kept while executing placement policy.
            1. While starting up the NN, SPS Xattrs checks happen even if feature disabled. This could potentially impact the startup speed.
