Enable the possibility of deploying multiple drivers when running TD distributed on K8s

### Expected Behaviour
The distributed execution should continue as long as there is at least one driver component running in the cluster.

### Actual Behaviour

### Reproduce Scenario (including but not limited to)

#### Steps to Reproduce

#### Platform and Version

#### Sample Code that illustrates the problem

#### Logs taken while reproducing problem

No files or tests are identified in the issue. Start by locating the distributed execution entry point and the Kubernetes driver lifecycle, then trace how execution reacts when a driver stops. Done means distributed execution continues while at least one driver component remains running in the cluster, with coverage for multiple drivers.
