The znc package installs the client but does not set it up as a
service.  This patch restores the service configuration that
was done on wheezy/trusty.

Take changes to the tomcat6 default configuration and apply to tomcat7
configuration.  This was done by review of the diff between sovereign's
tomcat6 configuration and the default tomcat7 configuration.

The package solr installs and uses tomcat7.  Installing tomcat8 appears
to be a mistake for Debian Jessie.

Avoid using the Include directive.  Move most of the SSL configuration
to the global configuration and leave enabling the SSL engine to each
virtual host that wants to use it.

Using a different approach to maintain wheezy compatibility

Not awesome. We need a better alternative, ideally one with a better security stance.

Formatting the task names.

Use newer native "write HTTP" plugin to send metrics to Librato, if configured.
