Example retrieving request query strings

```go
package function
import (
"fmt"
"net/http"
)
func Handle(w http.ResponseWriter, r *http.Request) {
// Parses RawQuery and returns the corresponding
// values as a map[string][]string
// for more info https://golang.org/pkg/net/url/#URL.Query
query := r.URL.Query()
w.WriteHeader(http.StatusOK)
w.Write([]byte(fmt.Sprintf("id: %s", query.Get("id"))))
}
```

#### Advanced usage - Go sub-modules via `GO_REPLACE.txt`

For this example you will need to be using Go 1.13 or newer and Go modules, enable this via `faas-cli build --build-arg GO111MODULE=on`.
