[1.8.x] Fixed #24381 -- removed ForeignObjectRel opts and to_opts
These cached properies were causing problems with pickling, and in
addition they were confusingly defined: field.rel.model._meta was
not the same as field.rel.opts.
Instead users should use field.rel.related_model._meta inplace of
field.rel.opts, and field.rel.to._meta in place of field.rel.to_opts.
Backport of f95122e541df5bebb9b5ebb6226b0013e5edc893 from master
