puppetlabs-stdlib has to be >= 9.1 (since puppet-grafana v13)

[XMol]

Affected Puppet, Ruby, OS and module versions/distributions

• Module version: >= 13.0.0

How to reproduce (e.g Puppet code you use)

Combine puppet-grafana >= 13.0.0 with puppetlabs-stdlib <= 9.0.0

What are you seeing

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Unknown function: 'stdlib::to_yaml'. (file: /etc/puppetlabs/code/environments/puppet7/modules/grafana/templates/pdatasources.yaml.epp, line: 3, column: 5) on node datacenter-metrics.scc.kit.edu

Any additional information you'd like to impart

The dependencies on the puppetlabs-stdlib module need to be updated. Starting with puppet-grafava 13.0.0, at least version 9.1.0 of puppetlabs-stdlib needs to be provided, since the template pdatasources.yaml.epp calls the function stdlib::to_yaml, which did not exist earlier (though to_yaml does still work in latest release and is marked deprecated).

• puppetlabs-stdlib PR #1356 puts to_yaml into the stdlib namespace
• Next release after that was v9.1.0
• 5ca71b55eb54cdbf42d87c8f78c7ef4fd7259edb changes the pdatasources.yaml.epp, but not metadata.json
• Even in master, the lower bound for puppetlabs-stdlib is just 4.20.0
