index_parallel task fails if segmentGranularity has a timeZone

### Affected Version

0.18.0 and 0.18.1

### Description

#### Cluster size

- 1 master (coordinator/overlord)
- 1 router/broker
- 1 historical
- 3-10 middleManagers

#### Steps to reproduce the problem

- create and run an `index_parallel` task
- must include a `timeZone` in the `segmentGranularity` in the `granularitySpec` in the `dataSchema`
- must have `maxNumConcurrentSubTasks` greater than `1` in the `tuningConfig`
- must have `type` as `hashed` for `partitionsSpec` in `tuningConfig`

#### The error message or stack traces encountered.

The main error is the `ZipException`

The unzip fails because [`findPartitionFile`](https://github.com/apache/druid/blob/0.18.1/indexing-service/src/main/java/org/apache/druid/indexing/worker/IntermediaryDataManager.java#L338) fails to find the partition created during the `partial_index_generate` task. [`getPartition`](https://github.com/apache/druid/blob/0.18.1/indexing-service/src/main/java/org/apache/druid/indexing/worker/http/ShuffleResource.java#L73) returns the error message instead of the zip file. So the unzip fails.

The partition file is stored with the timezone offset in the path like this:
`2020-04-24T00:00:00.000-04:00/2020-04-25T00:00:00.000-04:00`
```
/tmp/intermediary-segments/index_parallel_datasource_1_iiocmdme_2020-06-04T23:15:56.314Z/2020-04-24T00:00:00.000-04:00/2020-04-25T00:00:00.000-04:00/1/partial_index_generate_datasource_1_cgdlipdp_2020-06-04T23:16:02.960Z
```

But the http request to `getPartition` uses the UTC time
`startTime=2020-04-24T04:00:00.000Z&endTime=2020-04-25T04:00:00.000Z`
```

#### Any debugging that you have already done

I'm not very familiar with the druid code so I'm not sure if there is a simple code fix. @jihoonson might know how to fix it, since he is working on https://github.com/apache/druid/issues/8061.

It looks like `startTime` and `endTime` param args are from
```
partial_index_merge
spec
ioConfig
partitionLocations
interval
```
Maybe you could store `interval` with the tz offset instead of the materialized UTC time?

Start with IntermediaryDataManager.findPartitionFile and ShuffleResource.getPartition, then trace how partial_index_merge passes partitionLocations.interval into PartialSegmentMergeTask.fetchSegmentFiles. Reproduce the index_parallel case with a timezone-aware segmentGranularity and hashed partitions. Done means the partition request resolves the stored timezone-offset path and the partial segment merge completes without the ZipException.
