Run InitSqlPipeline (#727)

* Run InitSqlPipeline

Added the main() method to InitSqlPipeline.

Added a Gradle task to run InitSqlPipeline from command line. This
task is meant for testing and experiments.

Corrected the file name prefix of Datastore export files. Should
be 'output-', defined as 'input-'.
