feat: BED-7498 batch node update

[bsheth711]

This PR adds the ability to batch update nodes.

A couple things to note:

• I ended up going with the UpdateNodes(nodes []*Node) error signature for the Batch interface because this allows me to use two different implementations for updating depending on the number of nodes being updated. If the update is below a certain threshold, LargeNodeUpdateThreshold (currently set to 1M nodes), we do the typical batched SQL UPDATE...SET.... Above that threshold, we instead do a COPY...FROM... into a temporary table for the transaction, and then MERGE INTO the nodes table. This seems to be marginally faster for 1M+ updates, and should have even better scalability for much larger updates.
• I added an optional BatchOption parameter to the BatchOperation function signature that allows one to set a BatchWriteSize for the BatchOperation
• I added a helper function in ops.go: func UpdateNodes(ctx context.Context, graphDB graph.Database, nodes []*graph.Node, batchSize ...int) error that I think should be the first tool users of DAWGS reach for when updating nodes
• I added a helper function (s *Node) StripAllPropertiesExcept(except ...string). The reason for this is if a developer is working with fully hydrated nodes in memory, but they only change one property and want to update all these nodes, we can cut down on a lot of network traffic to DB by removing all but the properties we care about before sending the nodes to the DB to be updated. The DB also does not need to bother parsing unnecessary information as well.
