add description of quotas to architecture.txt

[zooko]

and make it clear that leases, garbage collection, quotas, etc. are all not yet implemented

irc transcript:

<kpreid_> zooko: Can there be subdivisions (subleases?) of storage quotas? <zooko> Hm. Quotas are actually completely unimplemented and partially undesigned.

<zooko> So I would prefer if they were clearly described as such in the docs.

<zooko> Where did you find description of them?

<kpreid_> Well, I found description of leases in architecture.txt.

• zooko nods.

<kpreid_> But before I hit that, I was wondering about quotas.

<zooko> Okay. So in answer to your question: I don't know. ;-)

<kpreid_> "Can server owners establish storage quotas? Obviously they can limit the whole store, but can they grant sub-spaces to object creators?"

<zooko> We have a extensive, but not complete and not final, design for that.

<zooko> In which design, they can.

See also the QuotaManagement page. Perhaps architecture.txt ought to point to it?

Sounds reasonable to me.

docs updated, in ff1b2c770e1aa6f4, with a link to QuotaManagement . Does that make this ticket closeable? Maybe we should add a new ticket for "subdivisions of quotas", since that sounds pretty cool.
