Make CLO install channel change resilient

Cluster Logging Operator keeps changing the list of available channels.
On OCP version 4.19 stable-6.1 is not available anymore, while on 4.16
stable-6.3 is not available.

This patch probes the operator manifest to grab the latest available
channel and use that to install CLO.
