… to preserve FileSystem info
## What is the purpose of the change
Fix an FileNotFoundException in State Processor API when working with
savepoints on cloud storage
## Brief change log
- Use Path instead of a String Path.getPath() in StatePathExtractor to
preserve FileSystem info such that FileCopyFunction can copy files even if they
are on cloud storage.
## Verifying this change
I've tested this fix with Azure blob storage and AWS S3.
This change added tests and can be verified as follows:
- Manually create an S3 bucket or an Azure blob container
- Configure a Flink cluster with s3-fs-presto or azure-fs-haoop plugin
enabled
- Start a Flink a job and create a savepoint on S3/azure
- Use state processor API to transform the savepoint to a new one and store
it in a new location on S3/azure
- There should not FileNotFoundException
