The goimports tool does not check for trailing whitespaces in multiline strings. This commit adds a simple linter to address this deficiency. This change will also have the benefit of providing light linting of any non-go files. Change-Id: I253dd7c4895f476fa3a6f0c4fccf7c9cada16366changes/17/701417/2
