* Backend: Enable Go module graph pruning and lazy module loading This commit applies the changes by running `go mod tidy -go=1.17` to enable module graph pruning and lazy module loading supported by Go 1.17 or higher. Signed-off-by: Eng Zer Jun <engzerjun@gmail.com> * Backend: Move from io/ioutil to io and os package The io/ioutil package has been deprecated as of Go 1.16, see https://golang.org/doc/go1.16#ioutil. This commit replaces the existing io/ioutil functions with their new definitions in io and os packages. Signed-off-by: Eng Zer Jun <engzerjun@gmail.com>
