  1. Fix MQTT-C issue with TLS 1.3 session tickets 

    TLS 1.3 server may choose to issue new session ticket in the middle
of active connection. This will cause next mbedtls_ssl_read() or
mbedtls_ssl_write() to return MBEDTLS_ERR_SSL_RECEIVED_NEW_SESSION_TICKET.
This is not a real error, rather notification to the application
to save session ticket for later use. As TLS reconnection is out of
scope at this point we can safely ignore it and retry operation.

Please refer to mbedtls/programs/ssl/ssl_client2.c for session ticket
handling.
