Implement -Timeout

[JustinGrote]

A Timeout option would be helpful, for instance not hanging on managed identity if it is not available or responding and move on to the other options. This is natively supported in Azure.Identity and just needs to be passed through to ClientOptions

Makes sense for sure, thanks for the suggestion!

TimeoutSeconds is already implemented for the other interactive flows, but not -ManagedIdentity.

After doing some experimentation it seems that the ManagedIdentityCredential fully ignores all configuration and ClientOptions that has to do with delays or timeouts, so I'll likely have to implement it myself (which is also doable).

Some reading (which states that it should be improved but that's not my experience with it atm):
Azure/azure-sdk-for-net#29471

Might also reconsider and use the default credential.

Edit: Nvm somehow it started working. I'll implement it 👍
