......................................................................
rest_handler: add API versions and schema validation
The JSON based REST API currently has no version checking and also
does not use any JSON schema based validation yet. This patch adds
both. An X-ADMIN-PROTOCOL field in the HTTP header informs about
the API version (same style as the JSON interfaces defined in
GSMA SGP.32 and SGP.22 would use). For incoming messages, the
X-ADMIN-PROTOCOL field is checked to prevent outdated clients from
using the REST API.
The incoming and outgoing JSON messages are now validated against
JSON schema files. Those are the same JSON schema file which were
only provided for documentation purposes only before. Now those
files have been fixed up and moved to the priv directory, where
they are now actively used.

This description above describes only the basic concept of the REST API. To
give a system integrator a detailed overview
on how the requests/responses should look like three JSON schema files are
shipped with onomondo-eim:
-* contrib/rest_api_resource_schema.json: This schema describes a REST
resource. This is the format that the requests
+* priv/rest_api_resource_schema.json: This schema describes a REST resource.
This is the format that the requests
issued to the REST API should have.

formatted response that is received from the

formatted response that is received from the
REST API when the `lookup` operation is performed.
-* contrib/rest_api_info_schema.json: This schema that describes the JSON

+* priv/rest_api_info_schema.json: This schema that describes the JSON
formatted info page that is received when the
REST API is called without any parameters.
+#### HTTP Header
+
+When sending a REST request, the following additional HTTP header fields have
to be present. The `X-Admin-Protocol`
+field must match the NSS of the URN found in the `$id` field of the JSON
schema files.
+
+* Content-Type: application/json
+* X-Admin-Protocol: onomondo/eim/v1.0.0
+
+Note: Any REST response will also contain an `X-Admin-Protocol` field.
Applications may query the `eIM Information`
+(see above) to receive and check the current API version used on the REST API.
