Fixes #1188.

This is a draft until the v0.102.0 version of Collector is released, which will include the new max_log_size setting of the parser.

Testing notes

  1. helm install daemonset ./opentelemetry-collector --set presets.logsCollection.enabled=true --set image.repository="otel/opentelemetry-collector-k8s" --set command.name="otelcol-k8s" --set mode=daemonset
  2. k get cm daemonset-opentelemetry-collector-agent -o jsonpath='{.data.relay}:

[pkg/stanza] expose max log size option for the container parser (#33186
98b5dcf 
)

**Description:** <Describe what has changed.>
<!--Ex. Fixing a bug - Describe the bug and how this fixes the issue.
Ex. Adding a feature - Explain what this achieves.-->
The
[logsCollection](https://github.com/open-telemetry/opentelemetry-helm-charts/blob/ef0e1ac4f645cdbb9bd0108c76b1ed69e418430c/charts/opentelemetry-collector/values.yaml#L29C3-L37)
Helm preset provides the option to set the `maxRecombineLogSize`.
The `container` parser does not expose this option but rather sets it to
`102400` by default internally.
This PR is to make this option configurable so that the parser can be
used in the [Helm preset
seamlessly](open-telemetry/opentelemetry-helm-charts#1195).

**Link to tracking Issue:** <Issue number if applicable>

**Testing:** <Describe what testing was performed and which tests were
added.> Added.

**Documentation:** <Describe the documentation added.> Updated.

This should not get merged until the v0.102.0 version of Collector is released, which will include the new max_log_size setting of the parser.

There was an additional fix for the parser that did not make it to v0.102.0: open-telemetry/opentelemetry-collector-contrib#33353

I would suggest we wait for it, before doing the switch.

@TylerHelmuth finally the fixes are in. This one should be ready for a review now.

Test the produced configmap

  1. Run helm install daemonset ./charts/opentelemetry-collector --set presets.logsCollection.enabled=true --set image.repository="otel/opentelemetry-collector-k8s" --set command.name="otelcol-k8s" --set mode=daemonset --dry-run

  2. Verify the produced config:

    receivers:
      filelog:
        exclude:
        - /var/log/pods/default_daemonset-opentelemetry-collector*_*/opentelemetry-collector/*.log
        include:
        - /var/log/pods/*/*/*.log
        include_file_name: false
        include_file_path: true
        operators:
        - id: container-parser
          max_log_size: 102400
          type: container
        retry_on_failure:
          enabled: true
        start_at: end

Verify the produced log records

  1. helm install daemonset ./charts/opentelemetry-collector --set presets.logsCollection.enabled=true --set image.repository="otel/opentelemetry-collector-k8s" --set command.name="otelcol-k8s" --set mode=daemonset --set config.exporters.debug.verbosity="detailed"

  2. Verify that Resource attribute and log attributes are populated properly:
