+K option in vm.args

[benbro]

The vm.args template set +K true which was removed in otp 21.

Is +A30 better than then default +A10?

[ferd]

we should probably re-benchmark a few of these. It's obviously safe to remove +K as an option.
The +A30 option is probably not as useful as it once was either due to the dirty schedulers work. Chances are that to be equivalent we'd need to set +SDio 30 to be the same, but even then that might be much because scheduling NIFs is different than scheduling linked-in drivers.

I actually thought we already dropped +A.
