"Solver <class 'pyomo.contrib.appsi.base.SolverFactoryClass.register.<locals>.decorator.<locals>.LegacySolver'> is not available (NeedsCompiledExtension)" when attempting to call `appsi_ipopt`

@makansij is this still an issue for you or can this be closed?

Pid improvements

@dallan-keylogic I finally had some time to review this and left you lots of relatively minor comments.
