User reported issue with dockerhub image

[critzo]

A user who is testing out the Dockerhub image reported this issue which we should investigate:

@critzo do you have more details on the exact docker run command that was used? It seems to be the effect of running the container with the -immediate flag rather than -i or --immediate (please note the double --.)

e.g.

$ docker run measurementlab/murakami:armv7-latest -immediate
[...]
__main__.py: error: argument -i/--immediate: ignored explicit argument 'mmediate'
