Request hangs

[hubiierik]

When an request is issued to the Nahmii back-end,
it happens that the request hangs.

The internal feature NahmiiRequest is using super agent requests. The requests are made without timeout option.

Propose to add a timeout argument to the constructor of the NahmiRequests class.

Adding timeout to superagent works but there is a bug in superagent that impacts the way the timeout is reported.

Expected: ETIMEDOUT
Got: ABORTED

This means that unit tests must check for 'Abort' message at timeout instead of 'Response timeout'
The same issue also seems to have an impact on superagent retry feature where some claim that the retry feature does not work with superagent promise calls.

See: ladjs/superagent#1487
