Provide user with a link on solve failure

[MichaelPesce]

if a solve fails, provide user with a link that leads them to a page showing reasons why the solve might have failed

[ksbeattie]

@MichaelPesce any update on this?

This is in line with IDAES' future effort to improve model diagnostics and UI related functionality to facilitate ease-of-use, which could be incorporated across IDAES-dependent platforms later on. Something for us to keep in mind.

@andrewlee94 @dangunter would also know more about this effort once it evolves.

We also noted that you could start with displaying the IPOPT output that shows the iterations and error message, which isn't always too helpful, but it'd be a start (not sure if you have this already @MichaelPesce ).

The error we display when a solve fails is:
"The solver failed to converge to an optimal solution. This suggests that the user provided infeasible inputs or that the model is poorly scaled, poorly initialized, or degenerate."

This appears to be generated in watertap/core/util/initialization.py when the check_optimal_termination() function is called during a solve.
