Provide a way to ssh to the top-level host of a unit

[James Troup]

When investigating things like memory usage, it's not useful to look
at the container itself, you need to look at memory usage across the
host.

Right now, I have to run 'juju status APPLICATION/N' to figure out
which machine it's hosted on and then ssh to it. It'd be nice if I
could do 'juju ssh --host APPLICATION/N' to shorten this process.

@James Troup,

'juju ssh' provides this functionality since Juju 1.x. See more information in 'juju help ssh'. Here is the extract:

Connect to a mysql unit:

    juju ssh mysql/0

Sorry, we misunderstood the initial request. You're asking to go to the host of a container, which should be possible.
Do you care at all about nested containers? If we did have that case, would we just end up on the highest host?

[John A Meinel (jameinel)]

It certainly shouldn't be hard for us to do the lookup for you, and find the underlying machine for any unit before doing the SSH.

I can see arguments either way, but I think on balance the highest
host would be the least surprising behaviour.
