costerra v0.4.1

Changed

• Google Cloud Recommender: only the recommendations about the code are
  shown. Recommendations about other resources of the same projects (VMs,
  disks, IPs, Cloud SQL instances… that the code does not manage) are left
  out, instead of being listed under "From your cloud usage". Billing-account
  commitments are kept for the regions and machine families of the VMs of
  the code (resource-based) and for the services it uses (spend-based); the
  spend-based recommender is only queried when the code has such services,
  and resource-based commitments only in the regions with Compute Engine
  capacity. A note (--details) says how many were left out.
• Google recommendations are matched to more resources of the code: the VMs
  of a managed instance group (<base_instance_name>-xxxx) to the group,
  and the boot disk of a VM to the VM.

Fixed

• The same commitment recommendation for several regions was shown once.
