Can't use SegmentUriPush job

When running jobs like :
`pinot-admin.sh LaunchDataIngestionJob -jobSpecFile job.yaml`
with job.yaml a simple SegmentUriPush job type
Controller server raise a `HttpErorStatusException ... Could not find paramName tableName in path or query ...`

I think there is maybe an issue with [`FileUploadDownloadClient.getSegmentUriRequest`](https://github.com/apache/pinot/blob/master/pinot-common/src/main/java/org/apache/pinot/common/utils/FileUploadDownloadClient.java#L461).

It seems that in HttpClient RequestBuilder, when used with POST or PUT methods and no entity (which is the case here) choose to put the parameters (tableName) in a form entity ([RequestBuilder source](https://github.com/apache/httpcomponents-client/blob/54900db4653d7f207477e6ee40135b88e9bcf832/httpclient/src/main/java/org/apache/http/client/methods/RequestBuilder.java#L465))

Currently, the controller doesn't seems to accept this kind of way to pass the tableName as the method param is annotated with @QueryParam ([PinotSegmentUploadDownloadRestletResource.uploadSegmentAsJsonV2](https://github.com/apache/pinot/blob/4292356500870d960f016267660392550879c28d/pinot-controller/src/main/java/org/apache/pinot/controller/api/resources/PinotSegmentUploadDownloadRestletResource.java#L579))

It doesn't seem possible to influence RequestBuilder behavior about this. So my temporary working hack is to add `.setEntity(new StringEntity("", ContentType.DEFAULT_TEXT))` in the getSegmentUriRequest RequestBuilder initialisation

Not sure if the best fix is to change the client request or the controller server rest Api definition...
