Add a playbook that tests collectd 6 vs collectd5
The playbook will: * build collectd-6, collectd-latest and flask app containers * generate a set of collectd configs * launch the collectd-6, collectd-latest with the generated configs * run the flask app which has a http_server that receives metrics from collectd v5 and collectd v6 * display the received metrics from both versions of collectd Collectd v5 shows PUTVAL Collectd v6 shows PUTMETRIC The playbook takes the following parameters: * PR (optional) The PRID for an upstream collectd pull request that will be passed to the collectd 6 container build * plugin (optional) The name of the plugin that is bneing ported This will filter the received metrics to show the value passed. Additional updates to existing roles include: * run_collectd parameterises the collectd container name so that the role can be reused for launching multiple collectd containers by passing distinct names.
