Provide Docker image flavors to reduce size

[RohanNagar]

Describe the problem that this feature would solve

If someone is planning on using Thunder with DynamoDB, classes related to MongoDB are not needed.

We can reduce the size of a docker image by not compiling those MongoDB classes that would never be used. We should offer multiple flavors of Thunder with reduced sizes.

Describe the solution you'd like

Dockerfile that builds Thunder excluding certain java packages during compilation and publish those

A multi-module maven build might be the way to go, with each module implementing a DB type.
