How to redirect tfdbg dumping directory

[twangnh]

By default, tfdbg dumps saved tensors to /tmp, but in my case, /tmp is mount in /root , /root has only several G's space, running the example debug is not a problem, but when debugging large network, for which in one run will generate tensors that exceeds 10 G's memory, it would prompts space not enough.

The constructors LocalCLIDebugWrapperSession and LocalCLIDebugHook both have a keyword argument called dump_root, which allows you to specify where to dump the debug data.
