Running RHEL 7.1, puppetlabs-mysql is not idempotent.
After a second run, puppet tries to change the SElinux context:
/File[mysql-config-file]/seltype: seltype changed 'etc_t' to
'mysqld_etc_t'
Since packaging already manages SElinux labels, we should not let
Puppet doing it (default behavior).
This patch aims to set selinux_ignore_defaults to True for the
mysql-config-file File resource.
Thanks to that patch, Puppet will be indempotent between all runs on
RHEL platforms.
