Documentation Cleanup

[Marco Ceppi]

Hi Jujuians,

I've been reviewing the documentation and wanted to pose a few questions
about it's current structure. There seems to be a lot of duplication
between sections of the docs and worse these duplications are out of
sync.

I've listed a few key duplicates below:

- https://juju.ubuntu.com/docs/provider-configuration-ec2.html
- https://juju.ubuntu.com/docs/provider-configuration-local.html
-
https://juju.ubuntu.com/docs/getting-started.html#configuring-your-environment-using-ec2
-
https://juju.ubuntu.com/docs/getting-started.html#configuring-a-local-environment


I'm inclined to delete the first two pages and then finish/flesh out the
second two sections. Opinions?

Thanks,
Marco Ceppi
