This PR adds support for specifying a trigger-level `metricType` in the KEDA
trait, mapping to KEDA's `ScaleTriggers.metricType` field (`Utilization`,
`AverageValue` or `Value`).
This is required for compatibility with **KEDA v2.18+**, which removed the
deprecated `metadata.type` field for the `cpu` and `memory` scalers. Without a
way to set the trigger-level `metricType`, those scalers can no longer be
configured through the KEDA trait on recent KEDA versions.
### Changes
- Added the `MetricType` field to `KedaTrigger`
(`pkg/apis/camel/v1/trait/keda.go`), exposed as the `metric-type` trait
property and validated against the enum `Utilization`/`AverageValue`/`Value`.
- Added the `MetricType` field to the KEDA duck type `ScaleTriggers`
(`pkg/apis/duck/keda/v1alpha1/duck_types.go`).
- Propagated `MetricType` from the trait trigger to the generated
`ScaledObject` triggers (`pkg/trait/keda.go`).
- Regenerated CRDs and API docs.
- Added `TestKedaMetricType` covering a `cpu` trigger with `metricType:
Utilization`.
### Example
```yaml
traits:
keda:
triggers:
- type: cpu
metricType: Utilization
metadata:
value: "70"
```
## Release Note
```
Add metricType support to the KEDA trait triggers (required for cpu/memory
scalers on KEDA v2.18+).
```
