Need to change way to puppet.log for UI

[Anastasia Palkina]

1. Deploy any environment
2. Click "View logs" button on any node
3. Choose "Debug" level for puppet.log. No log entries match current filters. (see screen)

Cause is new logrotate rules. Now puppet logs are located in /var/log/docker-logs/remote/node-XXX.domain.tld/puppet-apply.log.1.gz on each node, not in /var/log/docker-logs/remote/node-XXX.domain.tld/puppet-apply.log

This should be fixed on nailgun/library side - settings.yaml needs to be updated or changes in logrorate should be reverted

Changing to python according to conversation with Mikhail Polenchuk.

[Matthew Mosesohn (raytrac3r)]

UI should be able to render the previously rotated log file for puppet-apply (puppet-apply.log.1.gz) because it's very common for this file to exceed the minimum threshold of 20mb and be rotated within 15mins. Not compressing this file or finding a workaround to compress every file _EXCEPT_ puppet-apply.log would be quite onerous. As a result, nailgun should render this file and concat it with puppet-apply.log, gunzipping it first.

I believe this is not a bug, but feature, since we never say we support logrotated logs on Fuel UI.

The patch that implements this support is prettu huge and unreviewable. It's to dangerous to merge it in 8.0.

Setting Won't fix for 8.0. I'm going to send email that proposes to remove Fuel Log Viewer in 9.0.
