Rename perfplat.dev to full dev domain

Maintaining 2 domain names in development is a pain, so we're just
going to use the full one.
Increase server_names_hash_bucket_size everywhere

Now that we have super long domain names in development, we're running
into an error with Nginx starting:

    2014/05/02 15:30:38 [emerg] 13185#0: could not build the server_names_hash, you should increase server_names_hash_bucket_size: 64

@robyoung and I can't imagine that this will cause any massive impact
on the machines that don't currently receive it (backend boxes etc),
so increase it across the board.
Add jenkins as host alias to jumpbox-1

So that scripts (ie sensu alerts) can access Jenkins to eg download
build artifacts.

Sensu check script for pp-smokey output

This script is run with a pp-smokey test name, ie `backdrop_read`. It
downloads the latest pp-smokey results from Jenkins and parses the
output. It returns an exit code which a Sensu check can interpret.
Add sensu::checks for each pp-smokey feature

These run on the monitoring box invoke the smoke test checker script
every minute.
