Change all PuppetDB canonical page link metadata to version 1.1

This accounts for moved and renamed pages as well as simple version bumps.
Change PuppetDB version warning to use page.canonical; do version bump

Since we went to the trouble of getting page.canonical right for Google,
we may as well consume it ourselves! This commit:

* Uses the canonical link metadata to decide where to punt a reader when
  the click the "whoa no, I want the NEW version" link in the sidebar
* Puts the warning in the PuppetDB 1 nav snippet, since 1.1 is the new hotness
* Whoops, the 1.1 nav snippet said it was for 1, fix that too
Fix "todo" experimental link in connect_puppet_master.markdown

Replace it with like FOUR links instead
