The initial read(s) for reading in the HTTP request headers from the client did not make use of the `read_timeout`, and a client could cause a connection to hang forever. Also, there was no way to set the `read_timeout` for an `HttpSession` prior to this initial read, despite there being a `set_read_timeout`, so this commit also sets a "sensible default" of 60 seconds, which matches NGINX's default value for `client_header_timeout` and `client_body_timeout`.

The initial read(s) for reading in the HTTP request headers from the client did not make use of the
read_timeout, and a client could cause a connection to hang forever. This could allow to resource exhaustion attacks, as malicious actors could use up all available socket connections, or memory (since a buffer is allocated for each request)Also, there was no way to set the
read_timeoutfor anHttpSessionprior to this initial read, despite there being aset_read_timeout, so this commit also sets a "sensible default" of 60 seconds, which matches NGINX's default value forclient_header_timeoutandclient_body_timeout.See discussion at #447
