Serverless OwnTracks HTTP Backend

This is a implementation of the OwnTracks HTTP backend on AWS Lambda using serverless.

It currently implements:

• saving locations to DynamoDB
• a per-tid GeoJSON endpoint with points
• a per-tid GeoJSON endpoint with a linestring

There's no UI, but you can use https://github.com/dschep/geojson-viewer to visualize the GeoJSON endpoints.

# edit serverless.yml to set env vars
