Establish a hierarchy among documentation pages related to installation; ones about importing data and configuring server delegation

This commit clarifies the hierarchy among pages for installation by moving articles for importing data and server delegation under the "installation" section, as there are multiple documentation pages which discuss a similar topic and you can easily get lost in those pages.

Also: remove the anchor link to configuring-playbook-base-domain-serving.md from configuring-playbook.md, since that procedure is not required on configuring options but on finalizing the installation, which is discussed on installing.md after that page.
