Cleanup mount docs, remove redundant config, and set the default backup
mount. These change bring nspawn inline with our LXC capabilities. To
ensure the LXC and nspawn capabilities are on level footing, the read
only bind mount was removed.

Macvlan interfaces can have a user defined interface within the host
config. This change ensures that the capability, which is documented in
the nspawn_host role, is actually functional.

The changes here remove the boiler plate code we had in favor of using
all of our common roles. This also updates the nspawn role using some of
the learnings we've had from our recent LXC changes and ensures we're
not breaking any compatibility we had with our various distros.
Add option to run a full config update if required
> As a deployer I need the ability to make a sweeping change to container
configs if required. At present the nspawn container create role will
attempt to preserve the configs and update only what's required, which
is desirable when maintaining uptime. This change provides the option
`nspawn_container_preserve_config` which, if set to "false" will
template the container configs instead of trying to preserve it.
Document everything in config
