Read indices options in indices upgrade API (#21281)

With #21099 we removed support for the ignored allow_no_indices parameter in indices upgrade API. Truth is that ignore_unavailable and expand_wildcards were also ignored, in indices upgrade as well as upgrade status API. Those parameters are though supported internally and settable through java API, hence they should be all supported on the REST layer too.
