Guts: Make conditional link ("iflink") tags handle bare directory links properly

Links to /something/something/ go to /something/something/index.html,
but Apache handles that and Jekyll doesn't know it; page.url always has
the full filename. This commit teaches the conditional link tag about
index.html so we can link to /something/something/ in our sidebar pages.
Still can't link to /something/something and expect it to recognize it,
though.
mco: Add new comprehensive sidebar menu

This menu is complete -- it links to every single page in the MCollective docs.
mco: Remove outdated "Developer Info" pages from sidebar

These pages are only useful to RI, and have the potential to be
confusing to others.
Update templating docs -- replace link to external cheat sheat with inline syntax guide
Changes and additions to the console_auth page based on user and internal feedback. Hopefully this will ease the pain of setting up third party auth.
Added final copy edits, revisions based on feedback to PE 2.7 console_auth page, and also added the changes to the 2.6 page.
Guts: Add new docs mirror

We're going to replace mirror2 (enkal) with a box nearly identical to
web01. This adds it to the deploy pool; later, we'll remove mirror2.
Guts: Remove mirror2

And it's gone!

Multi-master: De-emphasize SRV records, and flag them as an experimental feature

This commit re-orders the options for distributing agent load and CA
traffic to put SRV records at the bottom. They're cool and they work,
but they have some pitfalls the user needs to know about, and the
feature could use some love before we can call it the preferred method.
Multi-master: Clarify a few things

I made a mistake in describing cert traffic as beginning with
/certificate -- thinking like auth.conf instead of thinking like Apache.
This commit clarifies that, as well as tells you basically all you need
to know for expanding the inventory service w/ PuppetDB.
