Is your feature request related to a problem? Please describe.

Currently, the awsecscontainermetricsreceiver returns "undefined" for ServiceName, see here. This is likely because this was implemented before ServiceName was available from the task metadata endpoint, however for Amazon ECS container agent versions 1.63.1 or later, it is available. 1.63.1 has been available for over 6 months now, and ServiceName should be added to the awsecscontainermetricsreceiver.

Describe the solution you'd like

Update the code for the awsecscontainermetricsreceiver to include ServiceName when receiving ECS container metrics.
