feat: permit abandoned data transfers to be re-started by another data-plane runtime

[ndr-brt]

What this PR changes/adds

Add the capability to the DataPlaneManager to pick up data transfers (DataFlows) "abandoned" by other runtimes.

BREAKING CHANGE: a new runtime_id column has been added in the edc_data_plane table

Why it does that

Permit data plane to be deployed in a clustered environment.

Further notes

• changed the runtime-id assignment logic, currently it was always set to a random value, but in fact it should also be assignable with the edc.runtime.id setting.
• added the isRunning capability to EmbeddedRuntime
• created a new mockito ArrayContainsMatcher that permits to match arguments when the passed array is contained in the actual one (necessary for unit-testing the flow lease behavior)

In a separate PR, can you update the Data Plane user document to describe cluster operations?
