Description

In hive, it support to create table whose name begins with digits. But in Flink, when using  Hive dialect to create such table like `default.3t`, it'll throw exception

Caused by: org.apache.flink.sql.parser.hive.impl.ParseException: Encountered ".3" at line 1, column 8.
Was expecting one of:
    <EOF> 
    "." ... 

We should make the behavior compatible with Hive instead of throw an exception when using Hive dialect.
