Add some global way (in the Kuadrant CR?) to configure the underlying components for them to push spans to the OTLP collector

[david-martin]

(split out from original body of work in Kuadrant/architecture#48)

When you create a Kuadrant CR, the kuadrant-operator creates & manages the corresponding Authorino & Limitador CRs (and operators).
If you want to configure tracing in either of those 2 components, you have to modify the Authorino or Limitador CR to add the tracing endpoint to the spec (as per instructions in https://docs.kuadrant.io/0.8.0/kuadrant-operator/doc/observability/tracing/)

To make the configuration easier, the tracing config for both CRs could be added to the Kuadrant CR spec.
The kuadrant-operator would take this configuration and set the configuration in the Authorino & Limitador CRs.
