Bindings configuration doesn't work with juju 2.2

[David Lawson]

I can only confirm this behavior with juju 2.2 but I was never able to get bindings to work with that version, no matter what format I tried specifying them in. I ended up getting past this by expressing bindings as constraints, which works fine. I suspect that this is a quoting issue, juju 2.2 expects bindings as --bindings "default-binding endpoint=other-binding" and it doesn't look like the code will result in the correct quoting, but that's just a guess.

As an aside, if there were an easy way to get the juju command lines that deployer is running out of deployer, with some kind of extra verbose debugging option, that would have made diagnosing this issue immensely easier.

On diff from bzr210 and bzr212, "--bind" uses "=" when it should use ":"

See diff: http://pastebin.ubuntu.com/24957168/
See docs: https://jujucharms.com/docs/2.1/charms-deploying#deploying-to-spaces

We will test such a change, and confirm.

--bind actually uses =, the docs are wrong, see https://github.com/juju/docs/issues/1931
