Deleting of ibm-licensing takes too long

[fketelaars]

Describe the bug
When running the cp4d-delete-instance.sh script, it waits unnecessarily long for the ibm-licensing namespace to be deleted. Even after the namespace has been successfully deleted, the script waits for 5 minutes before continuing.

Resolution

• The if [ "${FORCE_FINALIZER}" = "true" ] statement is incorrect, it should use ==. Can even delete this because of the 3rd change.
• Timeout is set to 300 seconds when the namespace is not deleted on the first check. Change this so that 60 second timeouts are applied
• FORCE_FINALIZER should be the default behaviour of the deletion. This is the only way to remove the CRs from the cluster once deletion is stuck. Remove parameter.
