Model runtimes tracking considerations

[GiudGiud]

Feature Description

We now track model runtimes when run by the CI
If we start reporting them in a public-facing website we should include some disclaimers because the CI isnt exactly running these models optimally. The difference between a run where you are going for performance and a CI run could be very high, probably at least 5x imo.

We don't want the VTB to be helping external actors draw bad conclusions about the performance of the codes

Design

Disclaimers
A help page on how to run the codes optimally ?

Impact

Stick to the original mission of the VTB

Maybe we can improve the disclaimer in the markdown file showed in https://github.com/idaholab/virtual_test_bed? We should possibly also include it in the webpage https://mooseframework.inl.gov/virtual_test_bed/.
