Description
Saw an exception in `FrontendIntegrationTest` during a travis build. Seems to be intermittent but filing this issue to keep track since
1) This is in the `stitchBlob` test (recently introduced)
2) We made some SSL changes recently
```
om.github.ambry.frontend.FrontendIntegrationTest > stitchedUploadTest[5] FAILED
java.util.concurrent.ExecutionException: javax.net.ssl.SSLException: SSLEngine closed already

Research direction
Start with FrontendIntegrationTest.stitchedUploadTest and the failing getBlobInfoAndVerify and uploadDataChunksAndVerify calls named in the stack trace. Run the stitched upload test and inspect FutureResult.java around resultOrThrow and get, along with the recent SSL changes. Done means the intermittent SSLEngine closed already failure is understood and the test passes reliably.
