2.4.1

⚠️ WARNING ⚠️

As described in #166 the upgrade path to this version might be broken on some systems.
To have a clean upgrade you need to turn promethus off before running a new version of this role. This is needed as we are modifying parameters of a user responsible for running prometheus binary.

Closed issues:

• When used on GCE with gce_sd_config discovery scrape config, the ProtectHome=Yes option prevents Prometheus to discover Google Cloud Instances #153

Merged pull requests:

• Add clarification surrounding when the .rules file is copied & where it goes #156 (wbh1)
• Resolves #153 prometheus homedir set to /tmp #155 (michalklempa)
• Document alert relabeling in README.md #152 (juliusv)
