getting stderr in slack callback plugin

[epiq sty]

Hello,

I am trying to setup notification to slack about failed ansible deploys. 

I am using slack callback plugin, but it's show only top level stats, without failure reasons.

I have found nice option in http://blog.cliffano.com/2014/04/06/human-readable-ansible-playbook-log-output-using-callback-plugin/ human_log.py but it's print only to console.

Sorry, I am pretty new to python developing, and can't convert logic from one python script to another quite fast;)

Maybe someone already already solved such issue , and have complete solution for such issue?

Thanks in advance!
