[RFE] Better control of what operator version is deployed

Feature Request

Is your feature request related to a problem? Please describe.
The way the operator is deployed through Subscriptions makes almost impossible to control what version of an operator is deployed. The solution proposed here consist of using startingCSV field + installPlanApproval: Manual in the Subscription. Than can be a relevant solution when managing a single cluster or a small number of clusters, but it's very difficult when you have dozens of clusters that need to be managed in an industrialized way (for example through GitOps).

Describe the solution you'd like
Adding an "endingCSV" field may be a possible solution.
