RDB Loader: remove VACUUM from transaction block

[abrenaut]

When running emr-etl-runner with the -i vacuum option I get the following error

Data loading error [Amazon](500310) Invalid operation: VACUUM cannot run inside a transaction block;

Redshift Cluster v 1.0.2058
emr-etl-runner r102_afontova_gora

Is this option still supported ?

Hi @abrenaut! This is indeed a bug, thanks for reporting. Scheduling.

From what I see in code - this should not be the case, as we run VACUUM outside of a transaction. I'll try to reproduce this later, but pushing back right now.
