Getting started cleanup

[mike-scott]

Fix some "easy" issues with our Getting Started documentation.

• Drop the CI selection page. Too complicated for a Getting Started guide.
• Move fioctl installation and build/deploy application pages out a level so that they apply to both the container-only and lmp-based workflows
• Fixup the title (grammar) for the "Building and Deploying an Application" page
