Task #2495
Task #1781: re-design benchmarking functionality
replace -noconfout with mdp option
Description
At https://gerrit.gromacs.org/#/c/7451 Berk suggested, and Erik and I agreed, that we replace mdrun -noconfout with an mdp option, which is on by default so that normal behaviour that normal users see stays the same. This option can be turned off when it is useful, e.g. in an .mdp file for benchmark tpr.

The proposal to have gmx benchmark replace gmx mdrun for that use case is a natural way to have the default for -c to be on or off in the two relevant cases.

BTW, there seems to be no documentation on what is the intended use of the confout file -- and perhaps have a conversation whether those functions can be served better by other mechanism in the future (e.g. checking that a simulation has completed).

Having the benchmark tool removes the (short term) need for an mdp option for confout.gro.
But the confout.gro file is an awkward construct for all its current uses. For capturing the state of the system for transfer between EM and MD tng would be a better option. For transfer between MD and MD a checkpoint works, although I'm not sure what happens when you change coupling algorithms etc.
And indeed we need a proper way of signaling that a simulation has finished successfully.
