* Update docs/submodules/yardstick from branch 'stable/euphrates'
  - BugFix: Fix to pod filename ext and prox path
    
    As per defect:
    - the "context:" stanza of every tc_prox_baremetal*.yaml"
     file has an incorrect pathname for the config file
    
    -  tc_prox_baremetal_binsearch.yaml and
    tc_prox_baremetal_ramp.yaml refer to
    "prox-baremetal.yml", which idoes not exist
    
    - incorrect prox bin path
    
    Resolution:
    - Unify the pod file name and path for all BM tests
    - Prox bin path changed to "/opt/nsb_bin/prox"
