state files

------------------------------------
Summary: DUCC SM: More robust logic to save state files
Key: UIMA-3742
URL: https://issues.apache.org/jira/browse/UIMA-3742
Project: UIMA
Issue Type: Improvement
Components: DUCC
Reporter: Jim Challenger
Assignee: Jim Challenger
The DUCC SM needs to use rename/create/remove logic to insure its state files aren't lost due to misc glitches. This applies to the .svc and .meta registration files.
Proposed logic is:
1. Rename affected file
2. Create new file
3. If 2 is successful, remove the old file, else try to rename it back and emit an error.
In no case do we want to lose a file, but we tolerate out-of-date state files.
