Create WPS Dispatcher for WIT Docker Container

[whatnick]

Create a dispatcher script packaged in a docker container that:

• Reads polygons from a PostgreSQL DB or Shapefile
• Dispatches these to polygon drill / csv creation functions in WPS
• Does this in batches and exits early if the target CSV already exists in S3
• Uses single-thread multi-container or multi-thread single-container approach , single-thread is preferred for Kubernetes paradigm.
• Times out failed polygon drills with estimated processing time derived from polygon area + heuristics
• Captures failed polygons for review
