[GOBBLIN-1480] Cleanup unused imports and enable checkstyle for them (#3320)

Previously, checkstyle was configured to check only a small subset of
things, and imports were not one of them. As a result, reviewers spend
their time commenting on code style, when it can be fully verified
automatically by CI job.

We enable unused/redundant import checks, and fix existing issues, so
that the build could complete successfully.

The only relevant change is in checkstyle.xml, all other files where
changed by IntelliJ "optimize imports" function. For most files it
just removed unused imports, but some of them had imports incorrectly
ordered, and IntelliJ fixed that as well.
