As mentioned in discussion #14426, the way that `cacerts` is handled by
cuttlefish schemas simply will not work if set.
If `cacerts` were set to a string value containing one X509 certificate,
it would eventually result in a crash because the `cacerts` ssl option
must be of [this type](https://www.erlang.org/doc/apps/ssl/ssl.html#t:client_option_cert/0):
```
{cacerts, CACerts :: [public_key:der_encoded()] | [public_key:combined_cert()]}
```
Neither of those are strings, of course.
This PR removes all use of `cacerts` in cuttlefish schemas. In addition,
it filters out `cacerts` and `certs_keys` from being JSON-encoded by an
HTTP API call to `/api/overview`. It _is_ technically possible to set
`cacerts` via `advanced.config`, so, if set, it would crash this API
call, as would `certs_keys`.
