Investigate whether we can run GrimoireLab

GrimoireLab is a toolset to gather and present OSS analytics and metrics, like "How long does it take us to close issues", "What is the distribution of contributions over individual contributors and companies".

More info: https://github.com/chaoss/grimoirelab

@sventiffe asked us to look into whether we can setup and host this.

Start by reviewing the GrimoireLab project at https://github.com/chaoss/grimoirelab and the repository's continuous-integration setup. Determine whether GrimoireLab can be set up and hosted for the requested OSS analytics, and document the feasibility, requirements, and proposed next steps.
