#23076: Should HSes use Stable nodes for services on long lived ports?

------------------------------+------------------------------
When a hidden service sets up its circuits, it uses
`rend_service_requires_uptime()` to check the type of service it's setting
up, and if it's setting up a long-lived service (e.g. SSH, etc.) it will
only use Stable nodes for its rendezvous circuits.
We should consider if this is a good idea wrt security, and potentially
kill this feature if we think it restricts our path selection too much or
reveals too much info to the RPs.
