Provide estimations related to storage

[demeringo]

Problem

Current cloud scanner does not take into account storage requirements.

Solution

Boavizta API provides data related to HDD / SSD, we could define a way to estimate the impacts of cloud resources related to storage.

Idea, similarly to what is done with the instances, retrieve impacts(type of storage / volume).

• Without detailled information from cloud providers, this means that we have to decide which storage archetype (or characteristics) from Boavizta API we want to map to a given storage type of the cloud provider.
• This mean also that we are likely to under-estimate the impacts (as we do not account for the control plan of storage)
• Decide if we count the "ordered capacity" (easier) or the "used capacity" of storage (more realistic, depending on storage type).

Object storage (like s3) will be implemented in a separate feature: #336

This should be split into 2 workstreams (and maybe 3 issues)

• VM disks
  • inventory of disks attached to VM
  • get estimations for disks
• S3 BUCKETS (in a separate feature Provide estimation of impact of S3 storage #336 )
  • inventory of S3 buckets (may require differents permissions)
  • get estimations for buckets

Verbose output fails when used in conjunction with the include_block_storage option:
