test.sh added for continious integration of PDI plugin

The script downloads PDI 7, and installs the build plugin + dependencies. Afterwards all defined tests from the test directory (./test/*.kjb) are executed.

For testing:
Test if the script executes the tests successfully in Ubuntu 16.04 and CentOS7. Afterwards modify the test that it fails, and check if it fails for CentOS7 and Ubuntu16.04.

After review and test are passed, the test script should be added to buildbot's CI suite.

more tests will be integrated tomorrow, then it'll get back to review.

Added a test.sh script that checks the tests sub-directories for kettle jobs and executes them. The defined jobs can have additional parameters defined in job.parameters which will be added during runtime.

Two CI tests are included so far:

• all type data ingestion check
• csv ingestion check (without verification, just checks if csv files can be injected)

This was merged so assuming review was good. Moving to test...

My assumption is that these tests will be part of the CI and regression tests for the version.
Let me know is this correct or I have to run them as separate test suite from somewhere.

Hi, yeah that's correct. The tests are part of the data-adapters regression suite invoked through make test.

You can manually execute just the regression test for the kettle adapter by running test.sh in the test directory.

1. Rename the adapter package name and related parts in test.sh script to refrect the recent changes. (mariadb-columnstore-kettle-bulk-exporter-plugin)
2. The check for installed pdi must include check also for installed mariadb connector. Currenlty if pdi is already installed the connectior will not be installed.

Made requested changes and included name change of MCOL-1470.

Test is the changed test.sh (to invoke manually our through make test)

Works fine, minor adjustments are needed. Will be reported as separate issues.
