For users who want to limit number of units to be printed, introduce an option "--max-print-units" for these commands: destroy, unload, stop, list-unit-files, and list-units.

Note that the default value of --max-print-units should be 0, which means "all units are printed", so that the default behavior should remain as before.

Fixes #1593

Fixes coreos#1593
Allow Cluster.WaitForN{UnitFiles,Units,ActiveUnits} to accept opts, an
optional string that contains parameters to be passed to fleetctl.
As it's supposed to be optional, we don't need to modify call sites
of those functions: no opts for WaitFor*() means no opts for
nc.Fleetctl().

It's a preparation for a new test that is supposed to pass
"--max-print-units" option to the fleetctl command.

TestMaxPrintUnits checks if the "--max-print-units" option works
correctly for commands like destroy, unload, stop, list-unit-files,
and list-units.

NACK, why bake this into fleet? This doesn't affect performance or anything, so can't people just use head?
