devbv opened a new issue #3032: HA controller lead to fail some tests
URL: https://github.com/apache/incubator-openwhisk/issues/3032
 
 
   Since Nginx does proxy in Round-Robin way, some tests which were designed to run sequentially in one controller are failed.
   
   Let me explain one example, travis of latest commit(0737826c06c73a904c49977910d103d1eed79174) failed the test "Wsk Package should allow updating a package". Because the result of package update was 409, not 200
   
   See the code below
   ``` 
   it should "allow updating a package" in withAssetCleaner(wskprops) { (wp, assetHelper) =>
       val name = "simplepackagetoupdate"
       assetHelper.withCleaner(wsk.pkg, name) { (pkg, _) =>
         pkg.create(name, params1)
         pkg.create(name, params2, update = true)
       }
     }
   ```
   
   It runs in this way
   ```
   1. delete pkg when withCleaner starts -> controller0 delete package if it exists
   2. pkg.create(name, params1) -> controller1 put package with rev A
   3. pkg.create(name, params1) -> controller0 put package with rev B
   4. delete pkg when withCleaner ends -> controller1 del package with rev A
   ```
   Package is finally stored with rev B, but controller1 try to delete it with rev A, and then CouchDB response last operation as a conflict(409)
   I found that many tests were failed by similar scenario while running Travis.
   
   Any good idea?
