qualified identifier

Description

• Add grammar rule for qualified name.
• Support Parsing for using qualified name as table name in DDL command CREATE TABLE and DROP TABLE.
• We can reuse the rule for qualified name for other SQL object in the future if needed.

Backward compatible:

I don't think this PR is backward incompatible as the new AST carries the notion of qualified identifier, and uses the identifier as the output for CREATE TABLE and DROP TABLE node.

The grammar rule changes affected the generated Antlr Parser but no user should directly invoke the Antlr generated parser anyway (i.e., The Antlr generated parser should not be sem-ver-ed in my opinion.)

The Pig AST remains unmodified.
