Add the possibility of partial loading

Related to the discussion at https://github.com/memgraph/gqlalchemy/issues/79.

Suppose we have a node defined:

class Stream(Node, labels={"User", "Stream"}):
    name: str = Field(index=True, unique=True, db=memgraph, label="User")
    id: str = Field(index=True, unique=True, db=memgraph)
    url: str = Field()
    followers: int = Field()
    createdAt: str = Field()
    totalViewCount: int = Field()
    description: str = Field()

And that we want to load all nodes that have followers = 500 from the database.

Something like:

streamers = memgraph.load_node_partial(Stream(followers=500))

Then streamers would be a list of all Stream nodes that have property followers set to 500. Then it won't be important that other properties are Optional and it is possible to get a list of matching streamers.
