Tablespace name LOGMINER_TBS should not be hardcoded in the Java code

Database administrators usually have their own conventions for naming tablespaces and other administrative Oracle stuff. Convincing them to allow a deviation from their conventions can be hard. So I think that it is not a good idea to hardcode the name of the tablespace LOGMINER_TBS in class io.debezium.connector.oracle.logminer.SqlUtils.

The easiest solution would be to just remove it from the CREATE TABLE statements. There should be no need to specify it explicitly since it is the default tablespace of user LOGMINER.
