Add experimental support for the JSON-RPC protocol (new connector)

[Sébastien Alix]

Create a new connector and service (into the 'oerplib.rpc' package) supporting JSON-RPC requests.
URL used by OpenERP : http://{server}:{port}/jsonrpc

[Sébastien Alix (sebastien-alix)]

Look at 'web/static/src/js/core.js:

        var payload = {
            jsonrpc: '2.0',
            method: 'call',
            params: params,
            id: _.uniqueId('r')
        };
        ...
        var request = this.rpc_function(url, payload).then(...)

Make HTTP requests on the 'http://{server}:{port}/jsonrpc' URL with these JSON data.

[Sébastien Alix (sebastien-alix)]

See source code of OpenERP (v6.1 and v7.0):

./openerp/wsgi/core.py:61:JSON_RPC_PATH = '/openerp/jsonrpc'
./openerp/wsgi/core.py:62:JSON_RPC_PATH_1 = '/openerp/jsonrpc/1'

but 'JSON_RPC_PATH' is never used.
