Allow reading Nomad CA/Client cert configuration (#15809)

* Allow reading Nomad CA/Client cert configuration

In the Nomad secret engine, writing to /nomad/config/access allows users
to specify a CA certificate and client credential pair. However, these
values are not in the read of the endpoint, making it hard for operators
to see if these values were specified and if they need to be rotated.

Add `ca_cert` and `client_cert` parameters to the response, eliding the
`client_key` parameter as it is more sensitive (and should most likely
be replaced at the same time as `client_cert`).
