feat: add minio profile

- add additional modules in Puppetfile
- update puppetlabs-lvm to 2.1.0
- add facts.d base path to hieradata
- add infra/storage and infra/storage/minio role data to hieradata
- add new facts for minio setup status
- add a static yaml minio-facts file to assist dynamic ruby facts
- updated hiera with additional directories (country/{role,region})
