Description
For large simulations, the ability to restart the simulations is vital.
We need to be able to save out the mesh, velocity field, current time step, end-time step state variables, and end-time step stress state. All the other data can be recovered from our initial data files. In order to do this we'll need to help expand some of the MFEM data collections for this purpose. Currently, the various data collections do not support saving out or loading QuadratureFunction data which is needed for the state variable and stress states.
Conduit and ADIOS2 data collections might be our best bet to get these fields implemented.

Research direction
The issue names no repository files, entry points, or tests. Start by reviewing MFEM data collections and the Conduit and ADIOS2 data collections mentioned, focusing on how mesh, velocity, time-step state, state variables, and stress state could be saved and loaded. Done means restart data can preserve the listed simulation state and recover the remaining data from initial files.
