Marco André Dinis 306d011151 Deprecate ca_signature_algo config (#13033) ...

After the merge of https://github.com/gravitational/teleport/pull/12674 we no longer use the following configuration:
```yaml
teleport:
    ca_signature_algo: "rsa-sha2-512"
```
As we now rely upon the `x/crypto` package to choose the signing algorithm (it defaults to `rsa-sha2-512`)

**Demo**
If we set `ca_signature_algo` (the value is irrelevant) and start `teleport` we get:
```shell
root@marco:/workspace# teleport start --debug
2022-06-02T09:33:58Z WARN             ca_signing_algo config option is deprecated and will be ignored, we'll always default to rsa-sha2-512. config/configuration.go:348
