Update "Chapter 1. Introduction to OpenStack High Availability in OpenStack High Availability Guide" to include HA concepts in context of OpenStack

[CloudDon]

Required:

1) Explain why HA is challenging in a OpenStack setup. The reader should be able to understand why HA is not 'turned on' by default in OpenStack.
2) Explain why 'HA is not a one-click feature' in OpenStack but requires a combination of tools/ configurations

Some example content to get our writers started would be great!

[Damia Pastor (magradallegir)]

Should I depict the stateless vs. the stateful components and the multiple approaches available? (e.g. Galera, RabbitMQ clusters)

[Tom Fifield (fifieldt)]

That sounds good!

[Lauren (laucon)]

I edited the patch and pushed it to git hub. I hope that works.

Guys, I edited the bug. I'm an outreachy intern applicant, so this was only my second contribution. But I hope the bit that I committed helped.
