Outdated Curl Version, Can't use curl with --unix-socket

[nasvillanueva]

I'm trying to make stackstorm call Docker API via curl but the one provided by the base image (ubuntu:trusty) is not updated and doesn't have any official package. On the other hand, ubuntu:xenial has curl 7.47 and --unix-socket was introduced in version 7.40

If I can find some time, I'll update the base image from ubuntu:trusty to ubuntu:xenial, test it then submit a PR for this.

We don't have any plans to make ubuntu:xenial as a base container for stackstorm Docker all-in-one version, see #29 why.

Oh, Okay then. If that's the case maybe I'll try building curl from source for the container. I'm not sure if it will work though.

I'll close this issue, but we can re-open in the future if necessary.
