MkDocs 1.1.1 breaks development server in Docker image

Description

When I try to run my Dockerfile to serve the mkdocs site locally, I get an error about the dev-addr

Expected behavior

I expect the mkdocs site to successfully load locally at http://0.0.0.0:8000/

Actual behavior

mkdocs gives this error:

INFO    -  Building documentation... 
ERROR   -  Config value: 'dev_addr'. Error: The MkDocs' server is intended for development purposes only. Therefore, '0.0.0.0' is not a supported IP address. Please use a third party production-ready server instead. 

Aborted with 1 Configuration Errors!

Steps to reproduce the bug

docker run --it -p 8000:8000 image-id

Package versions

• Python: python 3.6
• MkDocs: latest version on github (I clone the mkdocs-material in my Dockerfile)

We’re running in strict mode, meaning it’s an error. May want to call out that it’s no longer possible to use the flag in the latest version.

It’s only a warning. It was the deliberate decision of the MkDocs maintainers to leave it like that. Nothing we can do about, unfortunately.

@squidfunk Just want to say thanks so much for your advocacy on the mkdocs issue thread. It was nice to see a rational and compassionate approach. Looking forward to finding a solution as we also run in strict mode.
