Add content to help committers with hosted services/Google Analytics on a project website

Description

We should include more information about hosted services in general and the use of Google Analytics in particular to the Eclipse Project Handbook. This probably fits best in the "Resources" section.

Useful resources:

• Mike's statement on the topic [0]
• Chris' blog entry on the topic [1]
• Eclipse Foundation Hosted Services Privacy and Acceptable Usage Policy [2]

I'll take a pass at working Chris' blog post and Mike's statement into handbook content.
