TAJO-1220: Implement JDBC function for 'createStatement' and 'setEscapeP...

Hi guys!
- Statement createStatement(int resultSetType, int resultSetConcurrency)
   - The resultSetType is not supported 'TYPE_SCROLL_SENSITIVE'.
   - The resultSetConcurrency is supported only 'CONCUR_READ_ONLY'. 
- void setEscapeProcessing(boolean enable)
   - Tajo is not necessary the function. So do nothing.

Thanks.
