feat: integration test

[killme2008]

I hereby agree to the terms of the GreptimeDB CLA

What's changed and what's your intention?

Main changes:

• Move more cases from duckdb to our integration tests, there are still many works to do.
• Fixed some issues when moving tests:
  • Supports if not exists when creating a database, and supports create schema in the parser too.
  • Column's time index option doesn't support bigint type and it can't be present in the last column.
  • Supports unsigned integer types, but not implemented in parser yet.
• There are also some issues not fixed yet
  • Not expected to run ExecutionPlan more than once #790
  • Physical planner does not support subquery expression #791
  • Catalog manager register_schema should supports create_if_not_exists #789
  • Supports prepare and execute statement #769
  • Supports INSERT INTO SELECT statement #760
  • Supports default value when inserting data. #759
  • select sum(float64) returns wrong result. #829

Checklist

• I have written the necessary rustdoc comments.
• I have added the necessary unit tests and integration tests.

After merging the Arrow flight service, looks like all tests fail:

And I can't find a common characteristic from queries in optimizer/filter_push_down.sql. From the naming I would expect something like EXPLAIN rather than execute those SQLs.

It's moved from duckdb, and EXPLAIN will be test in optimizer cases.

Do you mean they will be added in the future? Maybe we can change it now, those queries have fewer means by executing themselves, and is not what the case name filter_push_down means.

Sorry, my mistake. I meant that the duckdb has a test suite for EXPLAIN command https://github.com/duckdb/duckdb/tree/master/test/sql/explain

We'll move them later.
