Added a make targets 'lint-style', 'lint-sanity', 'lint', and 'test'.

'lint-style' scans go files for formatting errors using 'gofmt'.
'lint-sanity' checks for common issues using 'go vet'.
'lint' is shorthand for 'lint-style' & 'lint-sanity'
'test' runs any existing tests using 'go test', and generates junit & coverage reports into tests/results/.
