[MINOR] proxy: provide function to retrieve backend/server pointers
int get_backend_server(const char *bk_name, const char *sv_name,
struct proxy **bk, struct server **sv);
This function scans the list of backends and servers to retrieve the first
backend and the first server with the given names, and sets them in both
parameters. It returns zero if either is not found, or non-zero and sets
the ones it did not found to NULL. If a NULL pointer is passed for the
backend, only the pointer to the server will be updated.
