PathConfiguration (Alluxio Core - Common Utilities 294 API)

All Known Implementing Classes:

PrefixPathConfiguration
```
public interface PathConfiguration
```
Path level configuration. An AlluxioConfiguration is set for each path pattern. This class matches an Alluxio path against the patterns, then from the configurations of the matched patterns, it chooses the configuration that contains the specified property key and belongs to the best matched pattern. Different implementations have different definitions of the best match.
