[pdm-devel] [PATCH proxmox v3 04/21] auth-api: extend `AuthContext` with prefixed cookie name

[Shannon Sterz <s.sterz@proxmox.com>]

this adds the function `prefixed_auth_cookie_name` to the
`AuthContext` trait. said function can be used by users of this crate
to modify the expected prefix of the auth cookie. most products
should be able to use the default of `__Host-` though, so this also
adds a default implementation.
