Allow for inifinite lease_seconds times about pubsubhubbub

[GoogleCodeExporter]

Just want to chime in on the ticket that I'd prefer to punt on how default 
behavior
is handled ... my preference short-term is to let hub implementation decide how
defaults work. As in, I'd prefer my hub to default to infinite, where others 
may want
to default to 30 days or something. 

Others may even want to make it explicitly required, but until we figure out an
agreeable default value, we leave it open to implementation. (This is not 
ideal, just
a way to be pragmatic about learning what the default should be before people 
start
expecting it to be one thing by it being encoded in the spec)

I think it should be easy for Subscribers to request infinite, without keeping 
much/any state or background lease renewals on their side.

I think the onus is on the hub to re-check subscribers and see if they're 
either/both 
1) still alive/reachable, 2) still wanting the subscription.

This is consistent with our philosophy of pushing all complexity towards the 
hub, and 
keeping the edges simple.  I personally was annoyed when I wrote my subscriber, 
having to deal with lease renewal logic.
