Remove usage of ansicolors

Ansicolors has a bug that causes builds logs to be huge
(several hundreds MB). Issue occurs randomly. As a result
Jenkins master spends most of the time waiting for the log
files written to GlusterFS.

Link to upstream bug in plugin:
https://github.com/jenkinsci/ansicolor-plugin/issues/67
