[YDB#1027] [V7.1-002] [GTM-F167609] SOCKET Devices support TLSv1.3 Post Handshake Authentication
When using TLS configuration verify-mode option SSL_VERIFY_PEER, GT.M enables TLSv1.3 Post Handshake Authentication (PHA) for client connections. When using TLS configuration verify-mode options SSL_VERIFY_PEER and SSL_VERIFY_POST_HANDSHAKE, GT.M enables TLSv1.3 PHA for server connections. By itself, SSL_VERIFY_POST_HANDSHAKE does not enable PHA. Previously, GT.M did not support TLSv1.3's PHA capability. This could cause problems when connecting to some TLSv1.3 servers that require PHA. (GTM-F167609)
