GetSmbFile and PutSmbFile has forced 5 sec timeout

It seems like timeout was introduced with the SmbjClientProviderService, and
SmbUtils.java defines the withTimeout setting from the underlying smbj library.

In SmbProperties.java, the default timeout value is set to 5 sec and you can configure it in the SmbjClientProviderService.

However, the older GetSmbFile and PutSmbFile processors uses SmbUtils.java as well, but the timeout configuration item is not exposed in their config ui.

The timeout setting should be added to the UI for GetSmbFile and PutSmbFile.

I think it's enough to add the following lines to PutSmbFile.java and GetSmbFile.java:

...
import static org.apache.nifi.smb.common.SmbProperties.TIMEOUT;
...
descriptors.add(TIMEOUT);
