(PDB-886) Drop [jetty] certificate-whitelist handling

Fully retire the accommodations for a (vestigial) certificate-whitelist
option in the [jetty] section.  The only valid location for that option
should now be [puppetdb].
(PDB-775) Tidy up acceptance helper for package based installs

This commit fixes an issue with package based acceptance tests
whereby we weren't applying the correct manifest for managing puppetdb
on either embedded or postgres puppetdb installs. The hsql issue was due
to the fact we weren't passing in `:embedded` to the module causing the
module to try and validate a postgres database, the postgres issue was
due to the fact that the db param to install_puppetdb is a keyword and
not a string so we were always applying the incorrect hsqldb manifest.

(PDB-353) Don't add new mbeans for metrics URLs.

- Added a check to ensure that requests for metrics/mbeans information
  do not cause creation of additional mbeans to track the metrics URLs.
  We check specifically for the "available mbeans list" URL, and for any
  specific metric URL from that list.
- Added test code to verify that :timers and :meters are not created
  when metrics-related URLs are accessed.

(PDB-840) Retire deprecated commands

This commit retires all of the previously deprecated commands and
removes all the associated support code for these commands, such as
validation of reports/catalogs for the deprecated versions. This commit
also updatees al the unit/integration tests to use the non-retired
versions of these commands and removes test code we no longer use.
