Multiline logs have newlines stripped

[andrzej-stencel]

Version: v3.0.0-beta.1
Container runtime: containerd

Describe the bug

When running the chart v3 with the default configuration in a cluster with containerd container runtime, multiline logs end up in Sumo without newlines.

Steps to reproduce:

Run the collection with default settings in a k8s cluster with containerd container runtime.

values.yaml:

sumologic:
  accessId: xxx
  accessKey: yyy
  clusterName: zzz

Expected output:

Multiline logs from containers should contain newlines:

{
    log:"2001-02-03 04:05:06 logger 1 log 2055 first line
      logger 1 log 2055 second line
      logger 1 log 2055 third line",
    stream:"stdout",
    timestamp:1674041362246
}

Actual output:

Logs from containers do not have newlines:

{
    log:"2001-02-03 04:05:06 logger 1 log 1252 first line  logger 1 log 1252 second line  logger 1 log 1252 third line",
    stream:"stdout",
    timestamp:1674041362246
}
