[SPARK-4239] [SQL] support view in HiveQl

Currently still not support view like 

CREATE VIEW view3(valoo) 
TBLPROPERTIES ("fear" = "factor")
AS SELECT upper(value) FROM src WHERE key=86;

because the text in metastore for this view is like

select \`_c0\` as \`valoo\` from (select upper(\`src\`.\`value\`) from \`default\`.\`src\` where ...) \`view3\`

while catalyst cannot resolve \`_c0\` for this query.
For view without colname definition in parentheses, it works fine.
I am wondering if we can just call the `HiveQl.createPlan()` directly here, since `alias` is not part of the `view`, and also, we may need to normalize the name of `view` or `alias`. Like below, `// Since HiveQL is case insensitive for table names we make them all lowercase.`
