Document Azure usage

[mrsimonemms]

Description

Add the documentation for Azure. As with everything, this has been based on the Civo stuff but Azurified.

Couple of notes:

• I would favour publishing Azure when we release v2.8 docs not v2.7. It's in from 2.7.4, so could be confusing if we get support requests for 2.7.0~3
• there are some outstanding images required. This shouldn't be published until they're added to this PR

As always, happy to do demos if required.

How to test

Run npm start and read things under the "Azure" tab.

Azure docs shouldn't be in 2.7 unless it's already release in 2.7.x. For now, it should only reside in v.next (the docs folder, not in any versioned_docs). If we release azure in 2.7.x, we will do what the last commit to this PR does, but if it's in a 2.8.X release, we will create a new docs version for 2.8, and automatically it will have Azure content as the new version for docs are a copy of v.next. Happy to discuss more if it's not clear. I created an issue to clarify how and where to add new feature docs #820 as it's not clear if you don't own the docs, sorry

@mrsimonemms Added some edits for ticky-tack language stuff. Otherwise LGTM 👍

Approved (with the caveat that this is merged into the versioning that @fharper suggested) I believe this is in the right "place"
