readlines() function in Python 3 returns list of byte objects instead of list of str objects. Since we shifted to centos 8 for collectd containers, Python 3 is used by collectd Python plugins. This patch fixes the issue that occured because of the change, by decoding the byte objects to utf-8. Change-Id: Ifff2c7c6c7d9adfcb524ed279e2a82aedfd4ce30
