Title: Add database migrations with Flyway.

Replaced DatabaseInitializer with migrations implemented with http://flywaydb.org/
Flyway keeps track in nflow_schema_version table what database scripts have been
executed. Renamed existing sql scripts as V2 scripts, because V1 is installing
nflow_schema_version table.
