IMPALA-6933: Avoids db name collisions for Kudu tests
Kudu tests generate temporary db names in a way so that its
unlikely, yet possible to collide. A recent test failure
indicates such a collision came up. The fix changes the
way that the name is generated so that it includes the
classes name for which the db name is generated. This db name
will make it easier to see which test created it and the name
will not collide with other names generated by other tests.
Testing:
- ran the updated test locally
