#4243: rend_consider_services_upload waits up to 4 hours to publish the first HS
descriptor by default

From the documentation comment on `rend_consider_services_upload` (in
src/or/rendservice.c):
{{{
* For the first upload, pick a random time between now and two periods
* from now, and pick it independently for each service.
}}}
âfirst uploadâ means the first HS descriptor upload after the service is
configured in the Tor instance (i.e. when Tor is started); the âperiodâ
referred to there is that specified in the `RendPostPeriod` configuration
option (default 2 hours).
Users have complained that HSes don't work for a while after they are set
up. Now we know why they don't work for a while.
Should this be changed? I assume this huge delay was intended to (a)
conceal associations between different hidden services run on the same Tor
client, and (b) try a little bit to conceal associations between hidden
services run on a relay and the relay's uptime. Do users really gain any
privacy/security/whatever from this delay? If so, how much?
If this shouldn't be changed, we need an FAQ entry about this somewhere.
