bundle2: expose mandatory params in a mandatorykeys attribute
We expose all keys that MUST be processed in ``part.mandatorykeys``. This makes
it much easier to access the information. Enforcement of the mandatory
parameters is coming in later changesets.
fixbundle() {
grep -v 'saving bundle' | grep -v 'saved backup' | \
grep -v added | grep -v adding | \
grep -v "unable to find 'e' for patching" | \
grep -v "e: No such file or directory"
