Return nailgun logs to fuel-logrotate

Recently fuel's logrotate configuration has been cleaned up from
duplicates and non-relevant docker folders. Also the nailgun's config
has been removed from the fuel's rotation since it has its own dedicated
rotation config. Unfortunately logrotate runs once a day which is not
enough for nailgun which generates gigabytes of logs in debug mode. This
commit returns nailgun's log rotation to fuel's config.

Also remove the native nailgun logrotate, since nailgun is not used
without Fuel in our configurations.
