Jorge Falcon 75f79dc866 Loadtest osquery perf workflow wording and enroll.sh remainder updates (#43762)
- Updates wording in `.github/workflows/loadtest-osquery-perf.yml` 
  - `4098` -> `4096`
- Removes: `(should be a multiple of 8, if setting
loadtest_containers_starting_index)`
- Updates `infrastructure/loadtesting/terraform/osquery_perf/enroll.sh`
to handle values that are not multiples of 8. If the value is not a
multiple of 8, logic has been added to apply the remainder.

## Summary by CodeRabbit

## Release Notes

* **Documentation**
* Updated load testing workflow configuration input descriptions for
improved clarity of parameters and their usage examples.

* **Bug Fixes**
* Fixed container count allocation logic in the load testing process to
ensure the final target count is always properly applied, even when
using increment values that don't divide evenly into the specified total
range.

Github Actions

Fleet uses Github Actions for continuous integration (CI). This document describes best practices and at patterns for writing and maintaining Fleet's Github Actions workflows.

Bash

By default, Github Actions sets the shell to bash -e for linux and MacOS runners. To help write safer bash scripts in run jobs and avoid common issues, override the default by adding the following to the workflow file

defaults:
  run:
    # fail-fast using bash -eo pipefail. See https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#exit-codes-and-error-action-preference
    shell: bash

By specifying the default shell to bash, some extra flags are set. The option pipefail changes the behaviour when using the pipe | operator such that if any command in a pipeline fails, that commands return code will be used a the return code for the whole pipeline. Consider the following example in test-go.yaml

    - name: Run Go Tests
      run: |
        # omitted ...
          make test-go 2>&1 | tee /tmp/gotest.log

If the pipefail option was not set, this job would always succeed because tee would always return success. This is not the intended behavior. Instead, we want the job to fail if make test-go fails.

Concurrency

Github Action runners are limited. If a lot of workflows are queued, they will wait in pending until a runner becomes available. This has caused issue in the past where workflows take an excessively long time to start. To help with this issue, use the following in workflows

# This allows a subsequently queued workflow run to interrupt previous runs
concurrency:
  group: ${{ github.workflow }}-${{ github.head_ref || github.run_id}}
  cancel-in-progress: true

When a workflow is triggered via a pull request, it will cancel previous running workflows for that pull request. This is especially useful when changes are pushed to a pull request frequently. Manually triggered workflows, workflows that run on a schedule, and workflows triggered by pushes to main are unaffected.
