rhts-report-result add support to $OUTPUTFILE or document it won't be supported

[bgoncalv]

When using restraint if no outputfile is provided to rhts-report-result it will try to upload the file set on $OUTPUTFILE.

Could tmt add the support for this or update the documentation to say this won't be supported?

@bgoncalv, who is / should be responsible for setting the OUTPUTFILE variable? Is this something that the test script expects to be set by default?

Yes, it is the test responsibility to set it, if the variable is not set than no log file will be uploaded in this case.
