Could not use GraphExecutor to load optimized models tuned before GraphRuntime renamed into GraphExecutor

[JC1DA]

I have a .so module tuned a month ago. When I tried to run that model with the latest tvm.
I noticed that tvm.contrib.graph_runtime was no longer supported. I have to use tvm.contrib.graph_executor instead.
(GraphRuntime was renamed as GraphExecutor from this commit 9b43a64 )

But when I loaded the module using graph_executor, I got this error
#########################
tvm.runtime.load_module(model_path)

TVMError: Binary was created using GraphRuntimeFactory but a loader of that name is not registered. Available loaders are GraphExecutorFactory, VMExecutable, metadata. Perhaps you need to recompile with this runtime enabled.

Can we add the support to load old modules using GraphExecutor?
Thanks in advance.

cc @areusch , we should perhaps add the loader registration of GraphRuntimeFactory back as an alias
