[receiver/splunkhec] Support passing access token via context

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

The Splunk HEC receiver currently sets an access token passthrough value as a resource attribute on the payload.

Describe the solution you'd like

Instead, the receiver should set this value in the context of the request so it may be passed around to exporters without exposing a secret in the data.

Describe alternatives you've considered

@atoulme hello teacher antoine, could I help in resolving this issue? I can inject it into req.Context and remove the corresponding pcommon.Resource.

hi, when I started working on this issue, it seemed unassigned, and I wasn’t aware of others planning to address it. I’d love to hear any feedback or suggestions to improve the solution.

You can take if you like, appreciated. This work is similar to what was done for SAPM receiver. I will review.
