### Environment

* Dubbo version: dubbo-2.6.4
* Operating System version: windows 10
* Java version: JDK1.8

When run the testcase(com.alibaba.dubbo.config.AbstractInterfaceConfigTest#checkApplication1) in windows environment,It will be wrong. 

So It should add scene judgement in windows environment(org.apache.dubbo.common.utils.ConfigUtils#loadProperties(java.lang.String, boolean, boolean),Line 220).

```java
if (fileName.startsWith("/")) {
````
change to
```java
if (fileName.startsWith("/")||fileName.matches("^[A-z]:\\\\\\S+$")) {
````
the testcase (com.alibaba.dubbo.config.AbstractInterfaceConfigTest#checkApplication1) will go well.
