Improve the documentation

Registered by Rob Cresswell

The docs have been fairly neglected for a while. A lot of the information is outdated and/or disorganised. We should do a pass over the information, removing or updating old parts, as well as filling gaps where we find them. We should also update the docs to match the visual style of the docs team.

The documentation structure will be based off the spec at https://review.openstack.org/#/c/472275/

- install/ --This will cover installation, deployment and configuration of Horizon and its plugins. If a
  consumer of Horizon is only interested in utilising it as part of their cloud, this section should provide
  all the information they need.
- contributor/ -- Anything having to do with contributing to the project. This will include developer
  setups, tutorial guides, and conceptual information. "Contributor" is important here, as it covers not
  just direct code contributions, but also content about packaging, reviewing, etc.
- configuration/ -- Detailed information about configuring Horizon. This would include all of the settings
  content.

Whiteboard

[amotoki - Jan 29, 2018] the most efforts have been done in Pike and we can improve our docs if we have more topics as a separate bug or blueprint. Let's close it.
[amotoki - Jan 22, 2018] Can we close this blueprint? Is there anything remaining in this blueprint?
