Nailgun api.log consumes 100% of disk space

[Alexander Rubtsov]

MOS: 9.2 (build 562)

This commit disables makes logrotate for Nailgun to be launched once per day rather than every 30 minutes as it was before:
https://git.openstack.org/cgit/openstack/fuel-library/commit/?id=0f27fc81a1cfab49647b09e9ff50f5d7d9f006c9

It may lead to situations where Nailgun log will consume all available space if it's growing too fast.
(e.g. DEBUG mode is enabled and the environment consists of many nodes).

Here is a sample from 80 nodes environment:
[root@fuel log]# cd nailgun/
[root@fuel nailgun]# ls -lrth
total 5.4G
-rw-r--r-- 1 root root 288 Sep 25 18:02 oswl_vm_collectord.log
-rw-r--r-- 1 root root 282 Sep 25 18:02 statsenderd.log
-rw-r--r-- 1 root root 297 Sep 25 18:02 oswl_image_collectord.log
-rw-r--r-- 1 root root 8.4K Sep 25 18:02 assassind.log
-rw-r--r-- 1 root root 321 Sep 25 18:02 oswl_keystone_user_collectord.log
-rw-r--r-- 1 root root 276 Sep 25 18:02 receiverd.log
-rw-r--r-- 1 root root 300 Sep 25 18:02 oswl_flavor_collectord.log
-rw-r--r-- 1 root root 300 Sep 25 18:02 oswl_tenant_collectord.log
-rw-r--r-- 1 root root 300 Sep 25 18:02 oswl_volume_collectord.log
-rw-r----- 1 root root 15M Sep 26 07:17 app.log
-rw-r--r-- 1 root root 5.4G Sep 26 07:17 api.log

If so, the Fuel master node may end up in inoperable state faster than the next scheduled rotation will be performed.

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.
