Bogdan DrutuandGitHub 7c2050acdb Avoid using interfaces/oneof like style for optional fields (#14333)
This changes how to handle optional primitive fields, instead of using a
"oneof" like style, define a metadata for each message that for the
moment only contains information if the optional fields are present of
not.

Alternative considered to use a pointer to the value instead of "any"
that would reduce the size of the field from 16B to 8B but would keep an
extra allocation.

**Before:**
```
BenchmarkMarshalAndUnmarshal/empty
BenchmarkMarshalAndUnmarshal/empty-12         	16115462	        73.64 ns/op	     224 B/op	       1 allocs/op
BenchmarkMarshalAndUnmarshal/all
BenchmarkMarshalAndUnmarshal/all-12           	 1844172	       641.0 ns/op	     800 B/op	      21 allocs/op
```

**After:**
```
BenchmarkMarshalAndUnmarshal/empty
BenchmarkMarshalAndUnmarshal/empty-12         	18948967	        62.91 ns/op	     208 B/op	       1 allocs/op
BenchmarkMarshalAndUnmarshal/all
BenchmarkMarshalAndUnmarshal/all-12           	 1914825	       624.3 ns/op	     760 B/op	      18 allocs/op
```

**Bechmark code:**
```golang
func BenchmarkMarshalAndUnmarshal(b *testing.B) {
	tests := map[string]*ExponentialHistogramDataPoint{
		"empty": NewExponentialHistogramDataPoint(),
		"all": GenTestExponentialHistogramDataPoint(),
	}
	for name, src := range tests {
		b.Run(name, func(b *testing.B) {
			buf := make([]byte, src.SizeProto())
			b.ReportAllocs()
			b.ResetTimer()
			for b.Loop() {
				gotSize := src.MarshalProto(buf)
				if len(buf) != gotSize {
					b.Fatalf("size mismatch: %d vs %d", len(buf), gotSize)
				}

				dest := NewExponentialHistogramDataPoint()
				if err := dest.UnmarshalProto(buf); err != nil {
					b.Fatal(err)
				}
			}
		})
	}
}
```
