`ManagedMetric` does not return the name of the Managed Resource

[rouzbehsedighi]

When using a ManagedMetric to collect status metrics from Crossplane-managed resources, the resulting metric data does not include the metadata.name of the managed resource (e.g., the name of btp-subaccount, or other managed resource being observed).

Since ManagedMetric does not allow projections, there is no way to include the name or identity of the resource in the metric output. This makes it impossible to distinguish which specific resource a given metric value belongs to.

Expected behavior

Each recorded metric from a ManagedMetric should:

• Include the metadata.name of the managed resource as a dimension (e.g., resource_name).
• Optionally include the namespace or other identifying fields.

This would enable distinguishing between metrics from multiple instances of the same kind.

@rouzbehsedighi I believe this is easy to fix, I am just thinking about what is the best way to define what I would call first level fields that can be added via configuration. If not possible for now, I will add it and think about a new way for future.
