Identify which Azure API can return inventory and instance usage

Problem

How to do inventory of azure resources in Rust.

The goal is to provide an inventory (including usage data) like we do for AWS.
This issue is more to research documentation about the crates and code we could use.

Additional context or elements

Boavizta API is evolving to return impacts of Azure resources.

• AZURE compute instances impacts boaviztapi#66
• Providing data for Azure virtual machines boaviztapi#282

List VM's:

https://github.com/Azure/azure-sdk-for-rust/blob/main/services/mgmt/compute/examples/vm_list.rs

Open questions:

• how to pass authentication parameters to the crate: likely this rust sdk follows conventions of other sdk's: https://devblogs.microsoft.com/azure-sdk/authentication-and-the-azure-sdk/
• how to retrieve VM CPU usage
• how to retrieve disk usage

[demeringo]

Data that we need to retrieve for VM's

• instance ID
• type of the instance
• array of tags (labels)
• cpu usage (CPU load in percent)
• region of use

Data that we need to retrieve for Block storage

• volume id
• storage type
• storage size (global volume size, i.e. this is expected to be higher than actual usage of the volume)
• array of tags (labels)
• region of use
• if possible : id of the VM to which the volume is attached
