Description of problem:

When uploading large config files the stream reset causes a stack trace: 

2016-06-30 15:33:07,478 [TP-Processor3] ERROR com.redhat.rhn.domain.config.ConfigurationFactory - IOException while reading config content from input stream!
java.io.IOException: mark/reset not supported
        at java.io.InputStream.reset(InputStream.java:352)
        at com.redhat.rhn.domain.config.ConfigurationFactory.bytesFromStream(ConfigurationFactory.java:856)
        at com.redhat.rhn.domain.config.ConfigurationFactory.createNewContentFromStream(ConfigurationFactory.java:824)
        at com.redhat.rhn.manager.configuration.ConfigFileBuilder.makeNewRevision(ConfigFileBuilder.java:169)
        at com.redhat.rhn.manager.configuration.ConfigFileBuilder.create(ConfigFileBuilder.java:113)

        at com.redhat.rhn.frontend.action.configuration.BaseAddFilesAction.execute(BaseAddFilesAction.java:66)

the above stacktrace occurs in ConfigurationFactory bytesFromStream

          stream.mark(size.intValue());
            do {
                read = stream.read(foo, offset, (foo.length - offset));
                offset += read;
            } while (read > 0 && offset < foo.length);
            stream.reset();


It looks like the following bug commit introduced this for some of the webui config uploads, bz 1091461

This issue looks fixed in spacewalk by wrapping the inputstream with a BufferedInputStream,

    Need to wrap the InputStream in order to support mark/reset so the binary upload won't crash anymore
