[docs] Ensure that crond is running in Keystone container

The commit message does not have a description, please provide more details: why was there DocImpact tag on this commit, is this something that should reflected in release notes, or user guide, or developer guide, what exactly is the visible impact of this change that needs to be explained in the documentation?

I agree with Dmitry - please, provide more information about place to put these changes.

Tomasz, please help us get additional information about what needs to be documented here.

As it states in description of the bug:

"This change brought running crond service in keystone container.
Such change should be reflected in Operators guide to they will be aware of the fact that there is a cron service running in keystone container now."

Ideally it would to put into "containers documentation" but we don't have it AFAIK, so it could be mentioned in Operators guide.

Cron service doing what? Why? What is the impact on the operator?
