Subject: [PATCH] feat(query-exposer): Add first draft of go application
This patch provides a simple go application that allows to
expose a single prometheus query, that exposes a single value
as an HTTP endpoint. While it sounds silly, this should be
enough to help with informing client software disconnected from
the cluster about the current status with alerting without
exposing more than the absolutely minimum amount of
information.

+A high-performance 100% compatible drop-in replacement of "encoding/json"
+
+# Benchmark
+
+
+
+Source code: https://github.com/json-iterator/go-benchmark/blob/master/src/github.com/json-iterator/go-benchmark/benchmark_medium_payload_test.go
+
+Raw Result (easyjson requires static code generation)
+
+| | ns/op | allocation bytes | allocation times |
+| --------------- | ----------- | ---------------- | ---------------- |
+| std decode | 35510 ns/op | 1960 B/op | 99 allocs/op |
+| easyjson decode | 8499 ns/op | 160 B/op | 4 allocs/op |
+| jsoniter decode | 5623 ns/op | 160 B/op | 3 allocs/op |
+| std encode | 2213 ns/op | 712 B/op | 5 allocs/op |
+| easyjson encode | 883 ns/op | 576 B/op | 3 allocs/op |
+| jsoniter encode | 837 ns/op | 384 B/op | 4 allocs/op |
+
+Always benchmark with your own workload.
+The result depends heavily on the data input.

+
+reflect api that avoids runtime reflect.Value cost
+
+* reflect get/set interface{}, with type checking
+* reflect get/set unsafe.Pointer, without type checking
+* `reflect2.TypeByName` works like `Class.forName` found in java
+
+[json-iterator](https://github.com/json-iterator/go) use this package to save runtime dispatching cost.
+This package is designed for low level libraries to optimize reflection performance.
+General application should still use reflect standard library.
+
+# reflect2.TypeByName
+
+```go
+// given package is github.com/your/awesome-package
+type MyStruct struct {
+ // ...
+}
+
+// will return the type
+reflect2.TypeByName("awesome-package.MyStruct")
+// however, if the type has not been used
+// it will be eliminated by compiler, so we can not get it in runtime
+```
+
+# reflect2 get/set interface{}
+
+```go
+valType := reflect2.TypeOf(1)
+i := 1
+j := 10
+valType.Set(&i, &j)
+// i will be 10
+```
+
+to get set `type`, always use its pointer `*type`
+
+# reflect2 get/set unsafe.Pointer
+
+```go
+valType := reflect2.TypeOf(1)
+i := 1
+j := 10
+valType.UnsafeSet(unsafe.Pointer(&i), unsafe.Pointer(&j))
+// i will be 10
+```
+
+to get set `type`, always use its pointer `*type`
+
+# benchmark
+
+Benchmark is not necessary for this package. It does nothing actually.
+As it is just a thin wrapper to make go runtime public.
+Both `reflect2` and `reflect` call same function
+provided by `runtime` package exposed by go language.
+
+# unsafe safety
+
+Instead of casting `[]byte` to `sliceHeader` in your application using unsafe.
+We can use reflect2 instead. This way, if `sliceHeader` changes in the future,
+only reflect2 need to be upgraded.
+
+reflect2 tries its best to keep the implementation same as reflect (by testing).
