Add progress output to Flyway migration process

[hectcastro]

I haven't tested a run where there are outstanding migrations to apply, but in scenarios where all outstanding migrations have been applied by Flyway, there appears to be no output to STDOUT. Having output in this scenario would be helpful to build confidence that the process completed successfully.
