Developer-roadmap: [Suggestion] Add Log Management tools to DevOps Path

[IuryAlves]

A log management tool isn`t always inside a monitoring tool.

It would be good to have a section about log management tools, like:

• Graylog
• Kibana + logstash
• Splunk

Don't forget papertrail! (=

• Papertrail - cloud-hosted log management, live in seconds || https://papertrailapp.com/

@damengilland How could I forget that :)! Will add the change this afternoon if I get chance.

Edit: Added in latest commit
