iotile-ext-cloud 1.1.0 regression

[mattrunchey]

The PR change to modify the way we support verifying a cloud connection (336a3d7#diff-9fe63ecc7aa07c80890100f03619b599L51) means that we can't verify without setting something in the iotile cloud registry:

self._conf.get('cloud:verify-server')

On the broker, we attempt to validate with a command line argument, since using the iotile config ... style is hard to use in that context. Basically, we call:

        cloud = IOTileCloud(retries=5, timeout=(5, 10), verify=args.skip_verify)

It would be nice to still support using verify as a direct argument passed to IOTileCloud instead of forcing it to go through an iotile:config registry value. Something like:

    def __init__(self, domain=None, username=None, arg_verify=None, **kwargs):
        reg = ComponentRegistry()
        self._conf = ConfigManager()

        if domain is None:
            domain = self._conf.get('cloud:server')

        if not self.verify_server:
            urllib3.disable_warnings(urllib3.exceptions.InsecureRequestWarning)

        _verify = arg_verify if arg_verify is not None else self.verify_server
        self.api = Api(domain=domain, verify=_verify, **kwargs)
        self._domain = self.api.domain
