Throttle tripleo-cd.sh

Prevent tripleo-cd.sh from spamming IRC channels when it encounters an
error that happens early in the devtest_overcloud.sh story by throttling
it to running at most once every 10 minutes.

Add some more details about os-collect-config

Flesh out some details about the hoops you need to jump through to
integrate the cfn collector into a heat template. This info could
probably live somewhere else, but I figure adding here is a reasonable
starting point.

Correct os-refresh-config README.md typo and format

Replace `run-parts' with `dib-run-parts' since os-refresh-config is
using it. Correct markdown code block format.

Updates .gitignore

To ignore swap files from getting into repository
currently the implemented ignore is *.swp
however vim adds more swap files if these files exists,
so improving this with *.sw?

Add diskimage-builder element.

Installs diskimage-builder from git. It's useful to have this in an
image since cloud instances themselves are often good build hosts to run
diskimage-builder (large amounts of ram for tmpfs, etc). Especially if
you have limited resources locally.

I considered adding this to the diskimage-builder repo instead of
tripleo-image-elements. If feedback suggests the other way, I'll submit
a patch for diskimage-builder instead.
