Description

This change introduces support for overriding the client display name used when attributing changes to the current client in the collab session. This can be used in scenarios where the client display name should be different from the default client display name, for instance, when client is running in app-only context.

This is achieved by adding a new optional property displayName to the ICollabSessionOptions interface. This interface is passed inside HostStoragePolicy which is specified when constructing document service factory. If displayName is specified, then it is used when establishing collab session and passed in the body of /joinSession request to Push service.
