Revert "ENH: In build.sh, run 'docker pull' to ensure we have the latest base."

This reverts commit 3f6cbcc229a32e21a6bb070f00cbf2f1bf168b48.

Contacting the network takes to long, as does downloading new base images when
they are not desired. For now, require the user to do this manually as
desired.
ENH: Add unified Docker build script.
ENH: Add unified Docker run script.
ENH: Start up nodeMirror before build is finished.
ENH: Add dockre logs when restarting container.

Some feedback to know what is happening.
