[JCZuurmond]

This PR add the option to use the authentication of the Azure CLI.

How do we improve testing here?

[JCZuurmond]

I think it would be neat to do something similar as they do here.

Looking at what is supported, we could add:

• AzureCliCredential (as done in this PR)
• CertificateCredential : allowing to have a certificate path instead off the secret.
• EnvironmentCredential : using environment variables.
• InteractiveBrowserCredential: login with browser.
• ManagedIdentityCredential: managed identity
• UsernamePasswordCredential: user-name password
• VisualStudioCodeCredential: visual studio code user.

Except for the ActiveDirectory Integrated (Windows only) it would cover all the currently supported login methods and more.

This is incredible, thanks! @NandanHegde15 and I were just talking about how
ActiveDirectoryIntegrated wasn't going to work because it requires Active Directory Federation Services which is not ideal IMHO.

[JCZuurmond]

Great, I can add the other authentication methods in separate PRs. I think we should do all authentications via azure.identity.

@JCZuurmond can you open this on https://github.com/mikaelene/dbt-sqlserver ? In #32 we're working on having dbt-synapse just inherit the connection class methods from dbt-sqlserver. In this way, one will also be able to use the Azure CLI to auth to Azure SQL
