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.

Initial commit for PuppetDB 1.1 docs (straight copy from 1.0)

This commit just makes a copy of the 1.0 PuppetDB docs into a new
1.1 folder; no other changes.  This way we'll be able to review
subsequent commits as diffs from the existing 1.0 docs.
Update 1.1 docs to include info about PuppetDB module

These changes came (roughly) from the README in the puppetdb source
tree; they add information about the option of installing and
configuring puppetdb from the PuppetDB module, in addition to the
other documented options.  The "install_via_module.markdown" will
probably need to be edited to directly include information from
the PuppetDB module's README_GETTING_STARTED.md, rather than
just linking to it, but I just wanted to get on the same page
with the docs team about the general organization of this before
putting more time into that.
