Redirect maas.ubuntu.com/docs* to docs.ubuntu.com

[nottrobin]

The MAAS 1.9 documentation is preserved on docs.ubuntu.com and the API docs are soon to be.

Once #34 is live, it is my plan to redirect all top level sets of documentation to their new home, and also setup specific redirects for pages which have somewhat sensible new homes:

Note that URLs not explicitly mentioned here, e.g. http://maas.ubuntu.com/docs2.1/enum.html, will simply forward through to docs.ubuntu.com and end up on a 404 page (https://docs.ubuntu.com/maas/2.1/en/enum.html). I think this is the correct behaviour for pages where the content simply doesn't exist any more in any form.

@evilnick, @degville, @pmatulis please let me know if these redirects seem to make sense, or if there are others I should add.

That seems to cover everything I can think of at the moment

This has been done.
