Simplifies the installation of kuadrant by removing the manual creation of ServiceMonitors, while also allowing users to disable the feature if they’d prefer to create them themselves.

Adding the capability to the sub-operators (authorino, dns, limitador) is out of scope at this time. The goal is to get the feature in front of users more quickly than the time it would take and risk of prioritising implementation in the individual sub-operators and bubbling that up to the kaudrant operator.
