I suppose it'd actually be enough to just move lxc-init to liblxc0, then
you'd only need to install liblxc0 in the container for lxc-execute to work.

Where to put the templates is an interesting question, I think properly
splitting to different packages will be tricky at the beginning, so I'd
propose we initially go for the very simple:

 - lxc (arch: any, contains all the lxc-* commands, init scripts,
templates, apparmor profiles, ...)
 - liblxc0 (arch: any, multi-arch, contains liblxc0 and lxc-init)
 - liblxc-dev (arch: all, contains the headers)
 - python3-lxc (arch: any, python module and python wrapper)

lxc depends on liblxc0 (and may depend on python3-lxc at some point)
python3-lxc depends on liblxc0 and recommends lxc
liblxc0 recommends lxc
liblxc-dev depends on liblxc0

That'd allow someone to use:
apt-get install --no-install-recommends liblxc0

And only get liblxc0 + lxc-init in a container.
