Clean up docs around local registry

* Remove duplicated info between the 'image-building' and 'multinode'
  guides regarding deploying a local insecure registry.

* Add a helper script to easily start a local registry in a consistent
  way.

* Remove warnings around bugs in older registries, 2.3+ is now the
  default

* Remove references to running the local registry on port 4000, this
  causes confusion as Docker expects port 5000 by default unless
  specified, and registries are not required for all-in-one deployments
  anyhow.

TrivialFix
