Be able to install pip packages using the docker image #1149

The current docker image uses a non-root user: https://github.com/locustio/locust/blob/master/Dockerfile#L18

That's great but it means it's not possible to install pip packages using this docker image:

$ docker run -it locustio/locust:0.13.0 sh -c "pip install --user boto"
