Cannot create table with "." in name

[matus-cuper]

Since Kafka allows dot character in topic names (for example my.test.topic) we use them as word separator. Unfortunately, connector attached to the topic with this name will try to create Scylla table dottest.my.test.topic and throw following exception:

...

	CREATE TABLE dottest.my.test.topic(

		lastName varchar,
		PRIMARY KEY(id))
	WITH compression = {'sstable_compression' : ''} (io.connect.scylladb.ScyllaDbSchemaBuilder:341)

Same problem with "-", which is OK in Kafka topics, but not OK in Scylla.
