Block Storage

Feature description

The OVHcloud CLI commands for managing block storage volumes have inconsistent naming between Manager/API and lack a retype feature ( edit --type) .

This issue aims to address these points by:

1- Adding the retype command for volumes  : edit <volumeId> --type <newType>
2- Renaming existing commands to harmonize them with the Manager and API
