Change default span/stat format configuration options
In preparation for 1.6.0 release, change the default span/stat formats to the following values, and remove the "experimental" keyword.

**pinpoint-collector.properties**
```
collector.experimental.span.format.compatibility.version=v1 -> collector.span.format.compatibility.version=v2
collector.experimental.stat.format.compatibility.version=v1 -> collector.stat.format.compatibility.version=v2
```
**pinpoint-web.properties**
```
web.experimental.span.format.compatibility.version=v1 -> web.span.format.compatibility.version=compatibilityMode
web.experimental.stat.format.compatibility.version=v1 -> web.stat.format.compatibility.version=compatibilityMode
```
