Apply model meta options as per-field overrides

[timkpaine]

FlowOptionsOverride.get_options replaced the accumulated options with model.meta.options instead of applying only the fields it sets, as the docstring and the other option layers do. Setting a single field such as cacheable in a model's meta therefore discarded the globally configured evaluator, log level, and any options given to the Flow.call decorator, and the model fell back to the default logging evaluator. Among other effects, its calls lost graph evaluator node reuse, so a dependency marked uncacheable ran twice when its parent called it again.
