"java.io.IOException: remote file operation failed" needs to be added to the naginator list of strings to look for to retry the build.

Windows builds will fail occasionally on remote file operation errors. This means they can't delete a file because it's currently in use because a program is running that has it open. We have resolved this issue by killing all known IoTivity test programs at the end of each run, but we don't retry the build yet if a failure was due to on the programs from a previous build keeping a file in the workspace open.

Adding the IOException should cause the build to retrigger after it's killed the offending process.
