Add/port metrics to the new Execution interface

[kaxil]

Find a way to emit metrics from the new supervisor process.

Some examples of what needs porting over:

airflow/airflow/jobs/local_task_job_runner.py

Line 224 in 84907f1

Stats.incr("local_task_job_prolonged_heartbeat_failure", 1, 1)

airflow/airflow/jobs/local_task_job_runner.py

Lines 347 to 361 in 84907f1

	def _log_return_code_metric(self, return_code: int):
	Stats.incr(
	"local_task_job.task_exit."
	f"{self.job.id}.{self.task_instance.dag_id}.{self.task_instance.task_id}.{return_code}"
	)
	# Same metric with tagging
	Stats.incr(
	"local_task_job.task_exit",
	tags={
	"job_id": self.job.id,
	"dag_id": self.task_instance.dag_id,
	"task_id": self.task_instance.task_id,
	"return_code": return_code,
	},
	)
