opamp: Adds support for v1beta1 OpenTelemetry Collector API in the OpAMP Bridge (#2985)
This change adds support for the OpAMP Bridge to manage and apply OpenTelemetry Collectors using the v1beta1 API in
the OpAMP Bridge. This change removes support for applying OpenTelemetry Collectors using the v1alpha1 API version.
The v1beta1 API is the latest version of the OpenTelemetry Collector API and is the recommended version for new
deployments.

collector: Since collector version 0.104.0 the collector listens on localhost instead of 0.0.0.0 by default (collector#8510). To avoid breaking changes the component.UseLocalHostAsDefaultHost feature-gate is disabled by the Operator. (#3119)
collector: Changes the default parser to silently fail. (#3133)
collector, target allocator: If the target allocator is enabled, the collector featuregate `confmap.unifyEnvVarExpansion' is disabled. (#3119)
operator: Release leader election lease on exit (#3058)
collector, target allocator, opamp: Enabling PodDnsConfig for OpenTelemetry Collector, TargetAllocator and OpAMPBridge. (#2658)
collector: Make the spec.mode field of the OpenTelemetryCollector Custom Resource (CR) immutable (#3055)
collector: Improves the performance of port and configuration parsing in the operator (#2603)

collector: Fixes a bug where an exporter would cause a port collision (#3124)
collector: Fix deletion issue of otelcol CR by making spec.config.service.pipelines.processors optional (#3075)
This change makes spec.config.service.pipelines.processors in OpenTelemetryCollector CRD optional, aligning with OTel Collector best practices. It resolves deletion issues by providing flexibility in CRD configuration, addressing conflicts between strict validation and practical uses.
Note: Updating the opentelemetrycollectors.opentelemetry.io CRD resource is required.
collector: Allow annotations on service account to prevent infinite reconciliation on OpenShift and creating infinite pull secrets. (#3106)
On OpenShift 4.16 the platform automatically adds an annotation openshift.io/internal-registry-pull-secret-ref: <simplest-collector-dockercfg-jwq66>
to the service account which contains secret name with image pull secret.
