Feature Request: Enable operator to pull the latest agent, and only pin to upstream version (Major or Minor)

[rhyas]

Can we please add a feature to the operator that enables automatic updating to the latest patch release? We don't really want to have to maintain static overrides when a patch release is made available.

For example, the current Operator is pinned to 7.54.0 but the agent released 7.54.1 that has some fixes we'd like to incorporate. In oder to do that, we have to override the Operators defaults in the CR. However, when the Operator gets updated, in order to get the current release, we'll have to go back in an undo that override. This is somewhat painful to keep track of, and it would be better if the Operator just kept to the current Minor release, or maybe even Major release. It could be an optional flag?
