Code Issues Proposed changes

Update git submodules 

* Update swift from branch 'master'
  to a9491eb7dada1afea882451335c56544936ce902
  - Merge "memcached: handle failed incr+add+incr better"
  - memcached: handle failed incr+add+incr better
    
    Improve the exception handling for the case when:
      * incr fails because key is not found
      * add fails because key is found (another actor added it
        concurrently)
      * incr fails because key is not found (the key expired since
        the add, presumably because the TTL was short relative to
        the execution time of the incr method)
    
    Previously this resulted in an error log and a traceback. This patch
    eliminates the traceback and adds the TTL to the log message.
    
    It's not clear that this failure scenario is due to a server problem:
    slow execution of the MemcacheRing.incr code path due to the green
    thread being suspended could cause the second incr to be delayed more
    than the TTL. This patch therefore prevents this particular failure
    scenario causing the server to be error limited.
    
    Closes-Bug: #2019095
