Tensorboard samples steps, yet users desire health pills at specific steps. This change makes the debugger plugin read directly from disk when the user specifies a specific step. This is much slower (It could take minutes.) than the alternative path of querying the multiplexer for sampled health pills.

These should have been done as part of an earlier change, but was missed.
Using name_scope means self.name = the_initialization_name + "/", which makes
it hard to set  a distribution name, then know what the name is later.

Change: 149990258

In the current PluginAsset api, the PluginAsset provides a serialize_to_directory method in which it directly writes contents to disk. This means that we as framework maintainers don't have the flexibility to change the serialization strategy in different contexts, e.g. providing good ways to serialize in contexts where we are writing to a db rather than to disk. Also, it presents a trivial landmine where users may use standard python file APIs rather than gfile and thus provide implementations that work externally but break within g3.

After the change, the PluginAsset instead provides an 'assets' method, which provides asset names and asset contents. How this gets written out is now an implementation detail handled by the tf.summary.FileWriter.

We haven't yet exposed the PluginAsset class as part of the TensorFlow API (it's hidden) so this isn't an API break.

Add a convenience method "forward_input_or_allocate_temp" to use buffer forwarding for temporary tensors.

Add buffer forwarding in a few additional places, including pooling ops and fused RNN kernels.
