Since the post_socket_cb() callback is added in struct network_helper_opts,
it's make sense to use it not only in __start_server(), but also in
connect_to_fd_opts(). Then it can be used to set TCP_CONGESTION sockopt.
Add a post_socket_opts type member cb_opts into struct network_helper_opts,
then cc can be moved into struct post_socket_opts from network_helper_opts.
Define a new callback cc_cb() to set TCP_CONGESTION sockopt, and set it to
post_socket_cb pointer.

From: Geliang Tang <tanggeliang@kylinos.cn>
This patch uses start_server_addr() in do_test() in prog_tests/bpf_tcp_ca.c
to accept a struct network_helper_opts argument instead of using
start_server() and settcpca(). Then change the type of the first paramenter
of do_test() into a struct network_helper_opts one.
Define its own opts for each test, set its own cc name into cb_opts.cc, and
cc_cb() into post_socket_cb callback, then pass it to do_test().
opts->cb_opts needs to be passed to post_socket_cb() in __start_server().

This patch uses connect_to_fd_opts() instead of using connect_fd_to_fd()
and settcpca() in do_test() in prog_tests/bpf_tcp_ca.c to accept a struct
network_helper_opts argument.
Then define a dctcp dedicated post_socket_cb callback stg_post_socket_cb(),
invoking both cc_cb() and bpf_map_update_elem() in it, and set it in
test_dctcp(). For passing map_fd into stg_post_socket_cb() callback, a new
member map_fd is added in struct post_socket_opts.

For getting rid of the second parameter of do_test(), this patch adds a
new callback post_connect_cb in struct network_helper_opts, it will be
invoked after connect_fd_to_addr() in connect_to_fd_opts().
Then define a dctcp dedicated post_connect_cb callback, invoking
bpf_map_lookup_elem() in it, named stg_post_connect_cb() and set it in
test_dctcp().
