Currently, ACM users are required to send all traces to a central location, which may not be suitable for all use cases. To address this, we need to provide flexibility in trace storage, allowing users to retain a subset of their traces locally within spoke clusters. This enhancement involves integrating Tempo, a distributed tracing backend, with the MCOA (Multicluster Observability Addon).

User story
As an ACM user, I want the option to store selected traces locally in my spoke clusters using Tempo, so that I can manage data locality according to my operational or regulatory requirements.

Acceptance Criteria

• Users can configure the storage of traces either centrally, locally, or both, using a clear and simple configuration interface.
• Ensure that traces stored locally are accessible and manageable similar to those sent to the central storage.
