Description

Currently, the result message of an index creation looks like that of a select query:

tpch> create index n_name_idx on nation (n_name);
Progress: 100%, response time: 0.241 sec
n_name
-------------------------------
(0 rows, 0.241 sec, 0 B selected)

We need to improve the message to be more helpful.
In addition, various kinds of errors such as FileAlreadyExistsException should be handled.
