Maven 3.8 now blocks HTTP repositories and only allows HTTPS. However, the version redshift jdbc dependency we are using connects to a separate repository that runs on HTTP. The latest version has switched to using HTTPS instead.
So this PR upgrades redshift dependency from version 2.0.0.1 to 2.0.0.4.
