[Bug] GetSourceAsync caches the wrong IMDS source

[bgavrilMS]

Library version used

4.84.0

.NET version

all

Scenario

ManagedIdentityClient - managed identity

Is this a new or an existing app?

None

Issue description and reproduction steps

If Azure SDK calls GetManagedIdentitySourceAsync it always detects V1 and caches it in that static value, and so it will always fail token binding. If you don't call that, it works because that value is not cached.

Proposal: simplify to return IMDS. probe only IMDSv1, assume IMDSv2 infrastructure is always there.
