Every ginkgo callback should return immediately when a timeout occurs or the
test run manually gets aborted with CTRL-C. To do that, they must take a ctx
parameter and pass it through to all code which might block.
This is a first automated step towards that: the additional parameter got added
with
sed -i 's/\(framework.ConformanceIt\|ginkgo.It\)\(.*\)func() {$/\1\2func(ctx context.Context) {/' \
$(git grep -l -e framework.ConformanceIt -e ginkgo.It )
$GOPATH/bin/goimports -w $(git status | grep modified: | sed -e 's/.* //')
log_test.go was left unchanged.
