Code Issues Proposed changes

Performance: use a single config file for logrotate 

Currently we generate a logrotate configuration file for each enabled
service. These are then included from a logrotate.d directory. With a
large number of hosts, this can take a long time to template.

Benchmarking of templating is available at [1].

This change switches to a single logrotate configuration file for all
services, with the include done locally using jinja. This should
drastically improve the performance of this task.

Partially-Implements: blueprint performance-improvements
