Description
When Calcite is pushing queries into the JDBC handler splitting the query via offset/limit can cause issues (RDBMs is not guaranteed to return the data in the same order every time.)
For these cases we want to:
a) Add a "do not split" flag to the jdbc handler. In that mode jdbc handler will skip the count and offset/limit processing but just run the query in a single node. Flag default will be false.
b) Have calcite automatically set this flag.
