Sebastiaan van Stijn dc66e6bad1 golangci-lint: use gci formatter instead of goimports
Most files already grouped imports into "stdlib -> other -> local",
but some files didn't. The gci formatter is similar to goimports, but
has better options to make sure imports are grouped in the expected
order (and to make sure no additional groups are present).

This formatter has a 'fix' function, so code can be re-formatted auto-
matically;

    golangci-lint run -v --fix
