send accepts options

Is this still valid?

i guess this makes no sense. and the adapter should not instantiate the guzzle client but accept it as constructor argument, so the options can be done on the guzzle client directly.

The constructor accepts a client, but if none is passed, one is created. This allows zero configuration.
