Allow callers to remove specific DV names from the wrt list (and the corresponding Jacobian blocks) of every constraint registered with pyOptSparse. This is needed when a DVGeo is attached to the StructProblem but the geometric DVs are not part of the optimization (e.g. structural sizing at a frozen jig shape), since the constraint sensitivities then also contain the geometric DV groups. Extracted from the aux_elem_dv_clean development branch so the feature can be used independently of the promoted-global-DV work. Co-authored-by: timryanb <41971846+timryanb@users.noreply.github.com>

Description
This PR adds a new optional argument
excludeWRTto the MACHStructProblem.addConstraintsPyOpt. It allows callers to remove specific DV names from the wrt list (and the corresponding Jacobian blocks) of every constraint registered with pyOptSparse.This is needed when a
DVGeois attached to theStructProblembut the geometric DVs are not part of the optimization (e.g. structural sizing at a frozen jig shape), since the constraint sensitivities then also contain the geometric DV groups.The parameter name and semantics are extracted from
aux_elem_dv_cleandevelopment branch (see PR here), so this can be used independently now.
