`TestLoadData` fails with Dolt integrator

[max-hoffman]

The LOAD DATA INFILE Enginetests that pass in GMS were never ran against the Dolt integrator.

I added skipped TestLoadData in dolt_engine_test.go.

These tests are failing because of mismatching directories as a result of running the test case in the Dolt integrator vs GMS itself. I don't think there's a great fix for this because you can't really specify the full path in the LOAD FILE query.

We do have sql-load-data.bats tests that do execute LOAD DATA queries against dolt.

I would prefer to close

Look at how i fixed this for setup scripts. The files need to be loaded into Go structs that can be accessed from GMS and integrator.

Going to close.
