Creation of

1. @fluidframework/client-common-utils
Purpose: to have common place that all client code can rely on, and reved with client mono-repo.
I believe most of common-utils should move into client-common-utils, but I'm too lazy to do it in one go.

2. @fluidframework/container-utils.
Purpose: for various stand-alone utilities that container provides, likely helper methods for error handling.

Better name suggestions are welcome!

With this, CustomErrorWithProps moved to #1 & CreateContainerError to # 2.
