Subject: [PATCH] rustls: Disable logging (#4426)

Disable logging of rustls to get rid off the following log lines:
```
Sending fatal alert BadCertificate
```

Upstream also removed them: https://github.com/rustls/rustls/pull/1278


Closes: https://github.com/paritytech/polkadot-sdk/issues/3252

+      The node was printing the following warning from time to time:
+      ```
+      Sending fatal alert BadCertificate
+      ```
+
+      This is not an user error and thus, the warning will now not be printed
+      anymore.
