[FEATURE REQ] Add metrics for Azure Spring Service Bus

[yiliuTo]

Context

We plan to expose metrics for Azure Spring Service Bus related libraries to enable developers to view metrics about connection, messages states.

Referring to Kafka's metrics design, the Spring Service Bus metrics components can contain:

Metric Name	Type	Tag	Description
connection.active	Gauge	servicebus	The number of active connection.
connection.opened	Gauge	servicebus	The number of open connection.
connection.closed	Gauge	servicebus	The number of closed connection.
messages.published	Count	servicebus, topic/queue	The number of published messages.
messages.failed_to_publish	Count	servicebus, topic/queue	The number of failed to publish messages.
messages.consumed	Count	servicebus, (topic + subscription)/queue	The number of consumed messages.
messages.acknowledged	Count	servicebus, (topic + Subscription)/queue	The number of acked messages.
messages.rejected	Count	servicebus, (topic + subscription)/queue	The number of rejected messages.

Next Step

To support Spring Service Bus metrics, currently we need the support from Service Bus SDK to enable and expose metrics APIs. Tracked in #25605
