Can spdk sock framework replace the default posix sock with libtpa?

[darrenwen0513]

Have an idea to integrate libtpa sock into the spdk framework.

Need to evaluate the feasibility:
1, libtpa has its own set of implementation mechanism, start an app, involving parameter parsing, configuration management, log management, thread management, and sock core, many places and spdk app startup coupling is very serious
2. If so, how much work is involved?
