[metricbeat] Add Windows service user name

[willemdh]

It would be nice if the windows service metricset would allow us to add the user configured for this service as windows.service.user.name. As some services (eg backup / Altiris / SAP) require elevated permissions, it would be useful to know where specific users are set etc..

@narph Is this start_name the same as service user name?

[narph]

a PR was built based on this initial issue #8561 (referenced above) and then a continuation PR based on the initial PR #11877, already merged.

The start_name should be the account name under which a service runs.
Depending on the service type, the account name may be in the form of "DomainName\Username" or UPN format ("Username@DomainName") etc.

This issue can be considered closed, we might want to rename start_name to user.name to follow ECS guidelines.

Sounds good, thanks @narph. I will close this issue and you can open a new issue to track the renaming work later.
