envconsul with Vault 1.20.2+ audience usage in k8s auth

[david-neilson]

Heya -- i was testing Vault in EKS using 1.20.2 and envconsul does not support currently audience which is a required property for k8s authentication which is going to be required in 1.21+

Documentation for reference of the announced requirement coming soon https://developer.hashicorp.com/vault/docs/auth/kubernetes#configuration

With the new requirement coming soon w/ vault envconsul passing this additional argument is going to be mandatory for some use-cases.

Can i get some eyes on this ? Or tag the correct people ?
