Modify limits fields according to microversion
1. Some limits fields are removed from Microversion 2.35/2.38/2.56,
so we should check limits fields according to microversion.
2. In test_max_metadata_exceed_limit, maxImageMeta is deprecated from
Microversion 2.38, so maxServerMeta is used instead, btw, maxServerMeta
seems to be more suitable for this testcase.
Besides, test_max_metadata_exceed_limit is not used in interop, so we
can safely change its name.
