Add GUC checks for ssl_min_protocol_version and ssl_max_protocol_version Mixing incorrect bounds set in the SSL context leads to confusing error messages generated by OpenSSL which are hard to act on. New checks are added within the GUC machinery to improve the user experience as they apply to any SSL implementation, not only OpenSSL, and doing the checks beforehand avoids the creation of a SSL during a reload (or startup) which we know will never be used anyway.
