Error handling / logging

A bunch of things going on here:

* Faraday middleware to facilitate logging of all requests/responses sent to the adapter
* Ability to capture errors that may occur on deployment creation and bubble them back up to the local agent
* Suppression of adapter errors that occur during `deployments#show` and `deployments#destroy`
* Global error handler for general error handling
