Verify that defining a new packaging release number with the -DMAXSCALE_BUILD_NUMBER=2 works and that a rebuild of an existing package correctly upgrades the package to the new one.
The steps to test are
- Build MaxScale normally
- Install MaxScale on a machine
- Build MaxScale again but this time with -DMAXSCALE_BUILD_NUMBER=2
- Check that MaxScale is upgraded to the package with the relese number set to 2
