Updated ansible packages fix security vulnerability

It was found that apt_key module does not properly verify key fingerprints, allowing remote adversary to create an OpenPGP key which matches the short key ID and inject this key instead of the correct key (CVE-2016-8614). It is reported that in Ansible, under some circumstances the mysql_user module may fail to correctly change a password. Thus an old password may still be active when it should have been changed (CVE-2016-8647). Data for lookup plugins used as variables was not being correctly marked as “unsafe” (CVE-2017-7481). The ansible package has been updated to version 2.3.1 to fix these issues and several other bugs.
