Draft: Bug 40547: Use container/remote_* from rbm
With rbm#40029 (closed), container/remote_* is now added directly to rbm, so we can remove it from rbm.conf.
We also need to rename a few options:
- var/container/use_container -> container/use_container
- var/container/global_disable -> container/global_disable
- var/container/disable_network -> container/disable_network
Closes #40547 (closed).
