e2e: create/delete snap and clone in parallel
In rbd E2E testing,we need to create snap and clone as parallel operation. This helps us to insure that functionality works when we have parallel delete and create operations and also it helps to catch bugs when we get parallel requests. Signed-off-by: Madhu Rajanna <madhupr007@gmail.com>
