example/nvmf: Deprecate spdk_thread_lib_init() by spdk_thread_lib_init_ext() 



Replace spdk_thread_lib_init() by spdk_thread_lib_init_ext() to
support dynamic SPDK thread scheduling in this sample application.

Add nvmf_reactor_thread_op() and nvmf_reactor_thread_op_supported(),
and then pass them by spdk_thread_lib_init_ext().
