Update git submodules

* Update docs/submodules/yardstick from branch 'master'
  - Merge "Add Flags class to base.Context"
  - Add Flags class to base.Context
    
    This patch adds a Flags class to represent the flags passed to
    the context.
    
    Flags will contain a set of attributes (for example no_setup and no_teardown).
    Those attributes will modify the behaviour of the context.
    
    The attributes added initially are:
    * 'no_setup' (default: False)
    * 'no_teardown' (default: False)
    
    In future patches, they will be used by the context to:
    * Change the name of the context.
    * Skip the deploy() and undeploy() methods to keep the VNFs active after the
      testcases are run.
