Add patchGraph() and maybe updateGraph() methods?

[lehni]

I would like to suggest the addition of patchGraph()that is similar to upsertGraph(), but would receive a sub-set of the full graph and just patch, without creating new instances in the graph, and throwing an error if data for new instances was included.

Perhaps it is then also worth considering updateGraph(), as a version of upsertGraph()that would just update and not create new instances?

And in symmetry to #556, it would then be great to then also add *AndFetch() versions of these: patchGraphAndFetch() and upsertGraphAndFetch().

I'm going to add options for upsertGraph that allow you to select any subset of [insert, update, delete, relate, unrelate] to be selected for an upsertGraph call. This case will be covered by only enabling update. Let's continue this discussion in #526

[lehni]

@koskimas there is a difference between update and patch, yes? would this cover both use-cases?

[koskimas]

upsertGraph always uses patch. It's possible to add an option for that too.

Thanks for clarifying! Those options sounds perfect, BTW.
