I've been using the valgrind publisher in an environment where
valgrind under some circumstances is not executed correctly leading to either missing, or malformed xml files.

Under normal conditions, valgrind reports errors for the project rather rarely (and the trend usually is at 0 for several builds).

This leads to a situation where errors can be missed, because it's not
easily visible if valgrind reported 0 errors, or if the publisher failed to read the valgrind output.

Hence, I've got a suggestion to improve the publisher plugin:
Would it be possible to add an option which fails the build in case no valgrind xml reports were found, or if one or more reports couldn't be parsed.
