(PDB-813) Upgrade trapperkeeper, and move certificate-whitelist

This patch upgrades trapperkeeper, and the jetty component to the latest
revision. All lines of this patch are attributable to getting this to
work.

The major change was the change to certificate-whitelist, which is
not supported in trapperkeeper-webserver-jetty9 so we had to intercept
the configuration item, deprecate it and move it to a new [puppetdb] section
so we could do this work ourselves.

We avoid using [global] in this instance, since we have identified
a potential to clash if we want to bundle PDB with other clojure applications,
this is a general problem anyway - but our first move to try and reduce
this potential.

Switch to using c3.large testing instances

This switches us over to the newer c3.large instance types in EC2. After some
testing I've found these boxes are much faster and can complete our tests at
a faster rate. Not only that for pricing they are priced at $0.105 versus
$0.130 (c1.medium) per instance hour.

And since c1.medium are now in the 'previous generation' bucket, best to switch
away anyway.

(PDB-900) Make performance improvements to fact_values GC process

Switched from a background thread to cleanup orphaned fact_values to one
that deletes as it goes. Switching to deferred constraints also
significantly improved performance on PostgreSQL. The same facilities are
not available in HSQLDB, but I have alternate queries that work, though
will likely not be as fast.
Mention that a -contrib package is required when install pg_trgm

Try reverting to c1.medium

After the change to c3.large we started to see intermitent issues with tests,
this patch is to just test the theory that it might be the box change
somehow changing the timing characteristics or some such. We're not 100%
so we might need to revert this also.
