Remove use of sslutils
sslutils is the only oslo-incubator module we use which registers any config options, and we don't even use those config options at runtime. The problem with us using oslo-incubator config options is that they need to be exactly in sync with the oslo-incubator version of those used by every project using oslo.messaging. Avoid all this be inlining validate_ssl_version() until we have it available in a real library. Change-Id: Id3b0bb2e7ede33ede9b66025d1af113ae60cfc58 Closes-Bug: #1287542
