Support CREATE GRAPH x, which indicates that graph x is persistent, and that the catalog has to be changed also in a persistent way.
Also support DROP GRAPH x, which indicates that a graph x that is persistent has to be deleted from Spark and the catalog.
CREATE GRAPH x should have a default semantics (for example, it should be default rule that indicates where graph x should be stored and in which format).
CREATE GRAPH x should also give the possibility to the user to specify some parameters such as directory where x is going to be stored, format for x, …
It could be something like CREATE GRAPH x (directory="/foo", format="parquet")
