Per issue MATH-902:
Its hard for me to read all the code, but at first pass it seems that in
BOBYQAOptimizer, maybe for others, no convergence criterion is set. So there is
actually no way to set the maximum number of iterations.
On that note. The optimization data is parsed at runtime, which is bad because
it leads to error prone code, since the user cannot tell that he is passing an
option that is ignored (or incorrect) until that line is actually executed
during runtime. In addition, if he is passing multiple options of the same base
class, something that is hard to notice unless you go down the hierarchy tree
for all your input classes, only the last option is actually set, without any
exception or warning given to the user.
