8373917: test/hotspot/jtreg/vmTestbase/nsk/monitoring: -iterations setting misused in tests

[kevinjwalls]

Some tests in test/hotspot/jtreg/vmTestbase/nsk tests are misusing the -iterations command-line option: it is parsed only as "-iterations x" rather than "-iterations=x"

Fixing the RunParams parsing to recognise this saves updating multiple tests.

Other options are "option=value" so accepting -iterations=number is what we might expect (and is what tests are currently written to use).

The change makes logs look correct. No more "Iterations: 0".

There are tests that currently log "Iterations: 0" but still do some work, so this is partly cosmetic, but also if you were thinking of making a test do some set limited number of iterations, you can now follow the example of other tests and have it work.
