NIFI-748 Fixed logic around handling partial query results from prove…
…nance repository
- Ensured that failures derived form correlating Document to its actual
provenance event do fail the entire query and produce partial results with
warning messages
- Refactored DocsReader.read() operation.
- Added test to validate two conditions where the such failures could occur

> Key: NIFI-748
> URL: https://issues.apache.org/jira/browse/NIFI-748
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Reporter: Mark Payne
> Assignee: Oleg Zhurakousky
> Fix For: 0.4.0
>
>
> We have a case where running with the prov being written to a disk that can
> be ejected. Disk was accidentally ejected while running. Provenance Event
> appears to have been indexed but event is not in the repo.
> Specifically, we are reaching Line 104 of DocsReader:
> {code}
> throw new IOException("Failed to find Provenance Event " + d);
> {code}
> As a result, searching for a specific Component ID is returning an error, so
> we can't search on that Component ID at all (unless we shrink the time range
> to a time when that didn't occur).
> We should generate a warning, and notify the user that X number of events
> could not be found and show what we can, rather than erroring out entirely.
