- Added two client certificate metrics for exec auth:
    - `rest_client_certificate_expiration_seconds` a gauge reporting the lifetime of the current client certificate. Reports the time of expiry in seconds since January 1, 1970 UTC.

 * **Handshake**: cipherSuite, localCertificates, localPrincipal, peerCertificates, peerPrincipal,
   tlsVersion
 * **HandshakeCertificates**: keyManager, trustManager
 * **Headers**: size
 * **HeldCertificate**: certificate, keyPair
 * **HttpLoggingInterceptor**: level
 * **HttpUrl**: encodedFragment, encodedPassword, encodedPath, encodedPathSegments, encodedQuery,
   encodedUsername, fragment, host, password, pathSegments, pathSize, port, query,

provide the password via:

```
export MINIO_KMS_KES_KEY_PASSWORD=<your-password>
```

Note that MinIO only supports encrypted private keys - not encrypted certificates.
Certificates are no secrets and sent in plaintext as part of the TLS handshake.
