commit ee3594072a7ef1c3f5661021fb31118069cbd646

    Mask passwords in exceptions and error messages
    
    When a ProcessExecutionError is thrown by processutils.ssh_execute(),
    the exception may contain information such as password. Upstream
    applications that just log the message (as several appear to do)
    could inadvertently expose these passwords to a user with read access to
    the log files. It is therefore considered prudent to invoke
    strutils.mask_password() on the command, stdout and stderr in the
    exception. A test case has been added (to oslo-incubator) in order to
    ensure that all three are properly masked.
    
    An earlier commit (853d8f9897f8563851441108a9be26b10908c076) failed
    to address ssh_execute(). This change set addresses ssh_execute.
    
    OSSA is aware of this change request.

  The ssh_execute method is still affected in Cinder and Nova Icehouse release.
  It is prone to password leak if:
  - passwords are used on the command line
  - execution fail
  - calling code catch and log the exception

  The missing fix from oslo-incubator to be merged is:
