HealthCheckThread is replaced by StartHealthCheck function in socket.cpp, but some of the docs/comments are not modified correspondingly. There are 3 files that HealthCheckThread is involved in:

• test/brpc_socket_unittest.cpp(3 occurrences)
• docs/cn/load_balancing.md(1 occurrence)
• src/brpc/socket.h(1 occurrence)

All sentences with 'HealthCheckThread' should be rewritten to sync with the

Let's support at least reading "b3" header from a single string, most commonly traceid-spanid-1
It would also be nice to support optionally writing this, especially in message providers or others with constrained environments.

Expected behavior

As discussed on openzipkin/b3-propagation#21 and first implemented here: https://github.com/openzipkin/brave/blob/master/brave/src/main/java/bra

In our codebase, we push RequestContext and immediately run some code with try-with-resources.
For example:

try (SafeCloseable ignored = ctx.push()) {
    logger.trace(decorate(msg));
}

If RequestContext provides run(Runnable) or call(Callable) we can reduce boilerplate code and simplify it.

ctx.run(() -> logger.trace(decorate(msg));

This is inspired by g

We have a fancy logo from the new tokio website, we should go through the code base and update it in every spot we use the old one.
