Per the Breaking Changes section of the changelog for 0.50.0 linking to this PR, and as discussed in #23036 (comment), this is a known breaking change, albeit one that presents a blocker for many Vector users to taking recent versions of Vector.

As such, I'm creating this issue to document the concern and as a basis for putting up a PR to re-add support for Azure token auth via environment variables.

Problem

#23351 bumped the version of several Azure Rust SDKs to unblock various other features. However, due to the apparent abandonment of the azure_storage/_blobs crates, it was not possible at the time to bump those crates to the same version as azure_core and azure_identity. This, combined with the removal of EnvironmentCredential from recent versions of azure_identity, made it extremely difficult for Vector to continue supporting Azure token auth in general, and via environment variables in particular.

However, as there are obviously a number of other users of the Azure Rust SDK in the wild, there is prior art for re-adding support for token auth (see eg this comment referencing a PR in Metaswitch). This, combined with copying in EnvironmentCredential from older versions of azure_identity should make it possible to restore the missing functionality.

I'll be putting up a PR soon which does exactly that.
