feat(ci): build otel images and run integration tests with them

[Molter73]

Description

This enables building images with the opentelemetry output enabled, making it easier to run integration tests with it.

Since the grpc output already tests all kernels we support, these tests are only run on fedora-coreos.

Summary by CodeRabbit

• New Features

  • Integration tests now support configurable virtual machines and output formats, including OTLP for OpenTelemetry testing.
  • Test execution accepts the selected output format and produces more distinct log artifacts.
  • Container builds now support reusable workflows and configurable build targets.

• Improvements

  • Automated builds, integration tests, performance tests, and Konflux tests now share consistent image tags and configuration.
  • OpenTelemetry-enabled images use the standard image build process.
  • Test environments default to gRPC output when no format is specified.
