feat(auth): add support for DefaultAzureCredential

[GabriFedi97]

Add support for authenticating to Azure via DefaultAzureCredential.
If the annotation barmancloud.cnpg.io/useDefaultAzureCredentials="true" is detected on the ObjectStore, in addition of setting the value .spec.configuration.azureCredentials.inheritFromAzureAD: true, the barman-cloud commands will be executed to use DefaultAzureCredential.

Fixes #662

We should not go ahead with this patch. Barman has added an explicit default option to the --azure-credential option. The API is stable, so we need to update github.com/cloudnative-pg/barman-cloud to support it and change the ObjectStore definition accordingly.

Do you know if that work is planned? Cause all I can find mentioned is this cloudnative-pg/barman-cloud#115 but that’s much older than this ticket.

Actually reviewing cloudnative-pg/barman-cloud#59 and https://github.com/cloudnative-pg/barman-cloud/pull/64/files

Does this not already chain to your linked commit and pass default in? Or can we not set the context flag without https://github.com/cloudnative-pg/barman-cloud/pull/115/files?
