Implement tests using utPLSQL and configure CI

[Pazus]

Hi. I'm a developer of utPLSQL v3 testing framework - https://github.com/utPLSQL/utPLSQL

Let me propose you to migrate your tests to utPLSQL. Any application has to be tests, otherwise how can you be sure that everything works as expected? And it so easy to create tests using the framework.

Documentation, examples etс are available here:
https://github.com/utPLSQL/utPLSQL/blob/master/docs/index.md
https://github.com/utPLSQL/utPLSQL-demo-project

Also you can see how we have established a CI infrastructure to test our builds using Travis CI.

If you have any qustions - feel free to contact us!
