[FEATURE] Support for other auth methods

[kenchan0130]

Is your feature request related to a problem? Please describe.

InutneCD only supports the client credential method (the client secret authentication）.
However, for local execution or for more secure secret management, another method is commonly used.

Describe the solution you'd like

I would like to see support for methods other than the client credential method (the client secret authentication）.

• Azure CLI authentication
• Client certificate authentication
• MSI authentication
• GitHub OIDC authentication

Describe alternatives you've considered

N/A

Additional context

The Graph API client used by azuread provider, which manages Azure AD with terraform, supports several auth methods.

Hi,

I'm currently working on switching ADAL over to MSAL as adal is deprecated. By doing this you will be able to use a certificate to authenticate or interactive mode to sign in with your account when running IntuneCD.

Currently, the MSAL Python module does not support Managed Identities (MSI). See this link for reference: https://msal-python.readthedocs.io/en/latest/#msal.PublicClientApplication.params.azure_region

Would it be enough with these authentication options?:

• Client Credential
• Cert
• Interactive

Managed Identities would be added when support is added to the MSAL module.
