Describe the bug

kyuubi returns http 500 response when user does DELETE on a non existing or cleaned up session id.

Line 155 in 494c425

@DELETE

Is a NotFoundException more appropriate like what we do for the get endpoint?:

kyuubi/kyuubi-server/src/main/scala/org/apache/kyuubi/server/api/v1/SessionsResource.scala

Line 68 in 494c425

@GET
