MINOR: add fetchs 'ssl_c_der' and 'ssl_f_der' to return DER formatted certs

ssl_c_der : binary

  incoming connection was made over an SSL/TLS transport layer. When used for
  an ACL, the value(s) to match against can be passed in hexadecimal form.

ssl_f_der : binary
  Returns the DER formatted certificate presented by the frontend when the
  incoming connection was made over an SSL/TLS transport layer. When used for
  an ACL, the value(s) to match against can be passed in hexadecimal form.
