Install is incompatible with pip 10.0

[jcberthon]

I have been trying to build a Docker image for glances, but I get the following error:

W: --force-yes is deprecated, use one of the options starting with --allow instead.

I've tried with Ubuntu Xenial and Bionic as base image. I've tried the develop and release/glances2 branches. Always the same error.

@jcberthon can you verify this isn't related to the pip10 bug pypa/pip#5240
