* Update docs/submodules/ccsdk/apps.git from branch 'master'
  to a0f6c597b54f42e141be6f41c6b228f4dc3ee988
  - Merge "Adding custom headers capability to REST client"
  - Adding custom headers capability to REST client
    
    For YANG PATCH requests to ODL to work, they need to have a Content-
    type header of application/yang.patch+json and should not have Accept
    as application/json
    
    Current REST client inserts a default header to the requests with this
    content:
    
      Content-Type: application/json
      Accept: application/json
    
    The solution was to add the possibility of sending custom headers alon-
    gside the other parameters.
