enhance: Make compaction log has traceID (#30338 )

See also #30167

After support open telemetry tracing, we want to have traceID as well,
this PR adds util functions to set traceID with span & propagate traceID
between different context.

Data Coordinator

Data cooridnator(datacoord for short) is the component to organize DataNodes and segments allocations.

Dependency

KV store: a kv store has all the meta info datacoord needs to operate. (etcd)
Message stream: a message stream to communicate statistics information with data nodes. (Pulsar)
Root Coordinator: timestamp, id and meta source.
Data Node(s): could be an instance or a cluster, actual worker group handles data modification operations.
