Dropping XML support

[marcc-orange]

The Orion Context Broker announced it will drop support XML after its next release.

We will also follow and drop XML.

Right now is there any way of using json responses in version 0.1.6? http://stackoverflow.com/questions/37208354/how-to-configure-cepheus-cep-so-it-returns-json-to-orion-instead-of-xml

@macu39 In 0.1.6, the Cepheus CEP and Broker support both XML and JSON formats of the NGSI v1 protocol. But the default format is still XML.
When Cepheus contacts a remote host without knowledge of its supported protocols, it uses the XML format for NGSIv1. This means that Cepheus 0.1.6 is not compatible with Orion 1.x and above.

The removal of the XML support in 0.1.7 will fix this issue as all requests will be expected to use the JSON format.

Just added an issue to track the compatibility problem #51

Removing XML support will be removed at later point. It is deprecated from 0.1.17.
