source: add a default value for search_drivers in POST /source

[ogayot]

For backward compatibility reasons with the desktop installer implementation, we now provide a default value (i.e., false) for the new search_drivers parameter in /source.

Running this through quick api test, the argument is still required.

  File "./v2", line 152, in auto_server_install
    await inst.post('/source', source_id='ubuntu-server')
  File "./v2", line 83, in post
    return await self.request('POST', query, data, **kwargs)
  File "./v2", line 110, in request
    raise ClientException(content)
__main__.ClientException: Traceback (most recent call last):

Well, that does not sound right :( The following command succeeds and does what it should do.

$ curl --unix-socket .subiquity/socket -X POST http://a/source'?source_id="ubuntu-server"'

I'm investigating.

Sorry, false alarm, my test was invalid.

No problem. I took the opportunity to add tests for it following your comment.
