Add timeout for time waiting for the first HTTP tracker request

[josecelano]

This adds a timeout to the HTTP tracker for the time the server waits for the first request from the client after opening a new HTTP connection.

It also adds a tower middleware for timeouts in requests.

To test the first case, you can open a connection to the API without sending any request with:

telnet 127.0.0.1 7070
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.

After 5 seconds you will see:

Connection closed by foreign host.

The current implementation for the first timeout does not send a 408 Request Timeout message. It seems it is also a common practice.

For advanced manual testing, you can use https://github.com/josecelano/axum-server-timeout
