Test parallel instance creation with --opportunistic-locking
With the recent changes, opportunistic locking should not
require retries any more on clusters that have enough capacity.
So it is fair to add the --opportunistic-locking option the
parallel instance creation tests. In this way, we
- verify that the absence of the need to retry is indeed true and
- get a realistic performance measurement for truly parallel
instance creation.

Clarify setup for parallel job execution performance test
Explicitly state, that parallelism enhancing options are to be used
in parallel performance tests, if it is best practice to use them on
the respective versions. A prerequisite for those options is that
using them does not require, even under heavy load but assuming enough
capacity in the cluster, any jobs to be retried.
