The request-promise-native package adds support for request with native
promises. This is a convenient way to synchronize multiple HTTP requests.
The functions are changed to use promises to make testing easier. With
promises, the testing code can use the chai-as-promised library.
There are a few cases where doRequest is called with a callback that again
calls doAsyncRequest. With multiple hosts, this causes each command to be
propagated to all servers. This is a design flaw of the current multi-host
mode and needs to be changed.
Changed maxctrl.js to wait on the promises to silence some warnings if the
promise rejections are ignored.
