tls_wrapper: use ENVOY_LOG instead of ENVOY_LOG_MISC

ENVOY_LOG_MISC should be used where no logger ID is available.

The SslSocketWrapper uses a logger ID and
should make use of this by using `ENVOY_LOG`.

This helps when filtering log messages by logger IDs.

In addition, this commit changes the current logger instance
`config` to `connection` - which is also used by the upstream
Envoy TransportSocket implementations.
