[SPARK-14460] [SQL] properly handling of column name contains space
## What changes were proposed in this pull request?
Although it is not recommended, table can be created with column name
containing space. For example,
>
create table test.people1 (name TEXT(32) NOT NULL,\`the id\` INTEGER NOT
NULL)
>
When we query the table via JDBC, we also need to escape the column name in
the same way if the column name contains space.
I've create a method to do the escape, it will only add backtick if column
name contains space.
## How was this patch tested?
I've updated the test case to test this scenario.
Other thought:
Is there any other cases we have to escape the column name? Or do we have
to always use backtick for each column name?
