Increase default session timeout longer than default manager heartbeat interval

See original GitHub issue

Currently SessionManager’s default heartbeat is 25 seconds and timeout is 5 seconds. So if there are no messages for a session within 5 seconds, the connection is closed.

If those are intended defaults, I would like to know why and it should be documented explicitly. If not, session timeout should become longer than heartbeat intervals by default to avoid confusion of new sockjs package users.

The 5 seconds timeout was taken from nodejs disconnect_delay: https://github.com/aio-libs/sockjs/commit/b0d7d17646527f89be172c092f9f69c5ffea8a97#diff-c4ae142f5c8b2a63ea9689afef142593

They are different parameters. nodejs disconnect_delay means interval to close the transport after client initiates the disconnect but the server does not respond (but it’s also used when initiating the connection): https://github.com/sockjs/sockjs-node/blob/4c9f3009be13962b0785138ccdf527c5abe925f6/lib/session.js

nodejs has a different heartbeat_delay for heartbeat, and it’s still different from the timeout: https://github.com/sockjs/sockjs-node/blob/4c9f3009be13962b0785138ccdf527c5abe925f6/lib/transport/websocket.js#L78

This was working fine until the heartbeat behavior silently changed: https://github.com/aio-libs/sockjs/commit/9c29e9921f815c0146882abab1240cd80473f4ab#diff-c4ae142f5c8b2a63ea9689afef142593R306
