doc: Update section about imperative containers

Browse Source 
Nix commands inside the container have been broken since 18.03,
and no fix is yet in sight.  Lets remove from the documentation
that this is a usecase that we support, as it doesn't seem
likely that this will be fixed before 18.09 either.

See #40355

Note that in previous versions of NixOS (17.09 and earlier) one could
also use all nix-related commands (like <command>nixos-rebuild switch</command>)
from inside the container. However, since the release of Nix 2.0 this
is not supported anymore. Supporting Nix commands inside the
container might be possible again in future versions. See

Alternatively, you can change the configuration from within the container
itself by running <command>nixos-rebuild switch</command> inside the
container. Note that the container by default does not have a copy of the
NixOS channel, so you should run <command>nix-channel --update</command>
first.
