observability context not propagated

[jonenst]

Describe the current behavior

when flushing, network-store uses many threads. It doesn't set the observability context. This leads to losing the traceid in the resttemplates to the network-store-server

Describe the expected behavior

network-store-server writes during flush should have the traceid
