The fromJson() function can take a map JSON and use it to set a map column. However, the specific example of a map<ascii, int> doesn't work in Scylla (it does work in Cassandra). The xfailing tests in this patch demonstrate this. Although the tests use perfectly legal ASCII, scylla fails the fromJson() function, with a misleading error. Refs #7949.
