merge: add a 'keepconflictparent' argument to graft

Before this change, `merge.graft` was always dropping the "grafted" changeset
from the parent. This is impractical in case of conflict as the second parent
can be useful to help with conflict resolution.

We add a new boolean parameter to control this behavior. This will make using
`merge.graft` directly in shelve practicable.
