      [CVE-2018-17187] transport TLS wrapper hostname verification mode not implemented

      Affects version: 0.3 to 0.29.0
      Fix Version: 0.30.0

      The Transport includes an optional wrapper layer to perform TLS,
      enabled by use of the 'transport.ssl(...)' methods. Unless a verification
      mode was explicitly configured, client and server modes previously defaulted
      as documented to not verifying a peer certificate, with options to
      configure this explicitly or select a certificate verification mode with or
      without hostname verification being performed.

      The latter hostname verifying mode was not previously implemented, with
      attempts to use it resulting in an exception. This left only the option to
      verify the certificate is trusted, leaving such a client vulnerable to
      Man In The Middle (MITM) attack.

      The change made here implements the VerifyMode#VERIFY_PEER_NAME config
      option, and makes it the default for client mode usage not configured

      Uses of the Proton-J protocol engine which do not utilise the optional
      transport TLS wrapper are not impacted, e.g. usage within Qpid JMS.
