Configure the SSL properties of the connection from provided config

This method was kept for backwards compatibility purposes.

The property {@link MetastoreConf.ConfVars#DBACCESS_SSL_PROPS} was deprecated in HIVE-20992 in favor of more
transparent and user-friendly properties.

Please use the MetastoreConf.ConfVars#DBACCESS_SSL_* instead. Setting those properties will overwrite the values
of the deprecated property.

The process of completely removing this property and its functionality is being tracked in HIVE-21024.
