syslogreceiver doesn't add resources

Component(s)

receiver/syslog

What happened?

Description

According to the doc, the syslog receiver can add resources to every incoming syslog via the "resource" key:

Field: resource
Default value: []
Description: A map of key: value labels to add to the entry's resource

However, it doesn't seem to actually add them.

Steps to Reproduce

Setup syslog receiver:

receivers:
  syslog:
    resource:
      mytag: myvalue
    udp:
      listen_address: "127.0.0.1:514"
    protocol: rfc3164

Send a syslog message:

logger -d fdkskjsdf --server=localhost --rfc3164

Expected Result

The ResourceLog should have a resource attribute "mytag" with the value "myvalue".

Actual Result

The ResourceLog does not have any resource attributes.

Collector version

0.96.0
