Validate a rpm packages signature.

This is the FileChecker passed down to the Fetcher to validate a provided rpm package.

This builtin checker includes the workflow communicating with the user in case of a problem with the package signature.

Exceptions
RpmSigCheckExceptionif the package is not accepted, propagating the users decision how to proceed (DownloadResolvableReport::Action).
Note
This check is also needed, if the the rpm is built locally by using delta rpms! \see RpmPackageProvider
