feat(components): add camel-observability-services

[squakez]

With this PR we're adding a new component which serves as an adapter and helper to expose a set of opinionated observability services. This first MVP adds camel-micrometer-prometheus components and a default configuration for it. Once this is onboarded I'll proceed with creating the proper extension/starter for the other runtimes.

Iteratively we'll be adding into this adapter a few more components in order to expose other sensitive observability metrics (telemetry, health, ...). The main goal is to provide services required when running a microservice oriented architecture on cloud, but the component can be used outside cloud as well with the same meaning.

Closes CAMEL-21384

@claudio4j @oscerd FYI. I am not sure if I've missed some configuration required to onboard the new component. Just let me know.

This looks good to me. This makes it easy by just adding the JAR and auto-configure.

LGTM, thanks.
