IMPALA-8636: fix flakiness of ACID INSERT tests

I had to add @UniqueDatabase.parametrize(sync_ddl=True) to some e2e
tests because they were broken in exhaustive mode. When the tests run
with sync_ddl=True then the test files are executed against multiple
impalads which means that each statement in the .test file is executed
against a random impalad.

> Impala should support insertion for insert-only ACID tables.
> For this we need to allocate a write ID for the target table, and write the data into the base/delta directories.
> INSERT operation should create a new delta directory with the allocated write ID.
> INSERT OVERWRITE should create a new base directory with the allocated write ID. This new base directory will only contain the data coming from this operation.
