Add Openshift Lightspeed integration guide

[mtodor]

This PR is adding instructions on how to setup Central and cluster in order to setup ACS->OLS integration.

Some decisions:

• I have added files and inline yaml to support users who want to simply use OC without copy pasting anything, just download file and run it. And other customers that have to adjust resource configuration.
• I didn't support configuration when lightspeed is not on the same cluster as central.
• Lightspeed configuration and setup is out of scope for this guide.
