MXS-1596 Test switchover under stress

Browse Source 
- Start 4 threads where each thread sits in a loop and performs
  20% updates and 80% selects. Each thread has a table of its own.
- The main thread executes the following in a loop.
- Perform a switchover from the current master to the next (which is
  simply the next node % all nodes).
- Keep on doing that for 1.5 minutes.

The expectation is that the switchover will succeed, that is, after the
operation there will be a new master.
