parameters as lists when evaluating `allowed_parameters` and `denied_parameters`.
For instance, configuring `denied_parameters` as `"Z": ["C", "D", ["C"], ["D"], ["C", "D"], ["D", "C"]]`
does not block requests that set `"Z": "C,D"` or `"Z": "D,C"`

Vault addressed the unexpected behavior of
`allowed_parameters` and `denied_parameters` in 1.21.x with
