Today, the Vault login url can take a query parameter specifying the login method. e.g. https://vault.com/ui/vault/auth?with=jwt . This lets people write documentation and share links to the Vault UI that has the jwt as the login method populated. There is a query parameter to support prefilling the namespace as well for Enterprise.

We like a query parameter in the url to specify the mount path as well (for customers who create auth mounts at a custom path). Curently, we have to share a url to the with jwt specified but document to users to specify the mount path

Describe the solution you'd like
