RFR: 8270344: Session resumption errors

[Sean Coffey]

Corner case where a session resumption can fail if the TLS server changes supported protocol versions in relation to a cached SSLSession. This is primarily an issue where the legacy TLS version is used in place of the newer "supported_versions" TLS extension.
