cmd/jujud: remove compatibility hacks

After some discussion with fwereade, we've decided
that these are unnecessary (and broken too - EnsureAPIInfo
only works pretty much by coincidence, and won't
work when the unit agent is connecting to the API).

If anyone is still running 1.10, they can still
upgrade, but they'll need to do it by upgrading via 1.12.

Please take a look.

LGTM. Would appreciate if you ran it past thumper too, just in case there's some
lxc-related wrinkle we're not aware of ourselves.

LGTM

LGTM

Containers don't depend on any of this.

It probably would make sense at some stage to have the lxc-provisioner task only
start if lxc is available.
That way our machine agents will work on windows machines (one day).
