mesh: Manage node config directory in mesh-config

This completely removes storage.c file. Instead, the handling
of mesh node configuration storage is done completely in
mesh-config layer by calling the following API functions:
bool mesh_config_load_nodes(const char *cfg_dir,
                            mesh_config_node_func_t cb,
                            void *user_data)

void mesh_config_release(struct mesh_config *cfg)
void mesh_config_destroy(struct mesh_config *cfg)

bool mesh_config_save(struct mesh_config *cfg, bool no_wait,
                      mesh_config_status_func_t cb, void *user_data)

struct mesh_config *mesh_config_create(const char *cfg_path,
                                       const uint8_t uuid[16],
                                       struct mesh_config_node *node)
