add node name to the labels of build metrics

[WenjunMao]

What feature do you want to see added?

I would like to request the addition of the node name to the labels of build metrics. This feature will allow users to easily identify which node was responsible for executing a particular build when analyzing metrics in Prometheus. Additionally, it can help users better understand and optimize cloud costs when using a cloud plugin for agents.
