- Added a config-mode flag in azure auth module to enable getting AAD token without spn: prefix in audience claim. When it's not specified, the default behavior doesn't change.

- `--api-audiences` now defaults to the `--service-account-issuer` if the issuer is provided but the API audience is not. ([#70308](https://github.com/kubernetes/kubernetes/pull/70308), [@mikedanese](https://github.com/mikedanese))

- Added audienceMatchPolicy field to AuthenticationConfiguration and support for configuring multiple audiences.
  The "audienceMatchPolicy" can be empty (or unset) when a single audience is specified in the "audiences" field.
  The "audienceMatchPolicy" must be set to "MatchAny" when multiple audiences are specified in the "audiences" field. ([#123165](https://github.com/kubernetes/kubernetes/pull/123165), [@aramase](https://github.com/aramase))

    * The audience claim before this fix has "spn:" prefix. After this fix, "spn:" prefix is omitted.

- Only extend token lifetimes when `--service-account-extend-token-expiration` is true and the requested token audiences are empty or exactly match all values for `--api-audiences`.
