Simplify the Getting Started experience

[ptgott]

This change makes the experience of getting started with Teleport more opinionated and more precisely molded around our intended audience. The assumption is that people who want to go through our getting started experience are skilled technologists who:

• Are curious about how Teleport works and want to tinker with a toy cluster
• Need to set up a production cluster in order to protect their infrastructure, in which case a toy cluster is less important than a way to get started with the real thing

Promote the "Linux Server" guide

Make the "Linux Server" guide the definitive introduction to OSS Teleport by removing other "Try out Teleport" guides and moving this one to the "Home" section. We want to remove the need for users to decide which getting started guide to try, and this guide is the only one that lets users spin up a fully fledged demo cluster besides the Digital Ocean guide.

To let users know about the DigitalOcean 1-Click droplet, this change links to our DigitalOcean 1-Click app from within the Linux Server guide. It also advises users who don't meet the Linux Server guide prerequisites to sign up for a Teleport Enterprise Cloud free trial.

This change also removes the Docker guide and redirects Docker-related traffic to the Installation page, since the Docker guide is more of a Getting Started guide than an integration guide, and our Installation page already includes Docker setup information.

Edit the Linux Server getting started guide

• Remove Application Service instructions, since it can turn off users who, for example, don't use Python or don't want to run the Application Service (plus we already mention it at the end of the guide for users who do want to run this service).

• Update installation instructions to use our one-liner.

• Make this guide more explicitly focused on the Open Source edition, removing Enterprise instructions. Users who want to tinker with Teleport will not be interested in the Enterprise edition.

• Add session recording instructions. Most of the content of the Linux Server guide has to do with setting up Teleport, rather than seeing Teleport features, so I wanted to adjust this balance a bit.

• Remove the permission warning. It takes up around 1/4 of the screen height when viewing the page, and we expect our intended audience to know this information already.

Change the Enterprise information architecture

• Remove the Enterprise "Getting Started" guide: This guide shows you how to deploy a demo Teleport Enterprise cluster, which is sort of a contradiction in terms. Enterprise users expect a production-grade cluster, which is not what you get in this guide.

• In the Enterprise Introduction page, include instructions to read the Deployment Guides, which show how to set up a mature HA deployment, plus a recommendation to use Teleport Enterprise Cloud unless you need the Enterprise-specific features explained in this guide.
