Merge pull request #7077 from ewolinetz/logging_facts_sane_yaml_parse

Automatic merge from submit-queue.

Only try to yaml.load a file if it ends in .yml or .yaml in logging facts

Addresses error seen in https://bugzilla.redhat.com/show_bug.cgi?id=1543625
Also prevents us from seeing this when rerunning a deployment for es5.x branch.

When we are trying to load a configmap file to parse it for facts based on the values, we should only parse if it is a yaml or yml file.

Note: if someone created a configmap entry with key that matched that, but wasn't a yaml file, it would still fail... not sure if that can be helped.
