To that end, I think SASL's confused everyone who's ever met it, and I
don't think anyone actually asked for it back in binprot days.

Said I was going to do this before but hadn't... Lets try something
simple, and if someone asks for SASL I think it's actually easy:

client connect:
set auth 0 0 [length]
username password
\r\n

... and if you get back a STORED, you're good to go. if you try to run any
other command you'll get:

CLIENT_ERROR unauthorized

password database is a username:password\n file on disk, reloaded when it
changes. no fancy datastructures so will get slow if people use a billion
users. user's don't do anything, but putting them there now in case we
ever decide to.

if we ever decide to support SASL again:

client connect:
get mech-list
MECH CRAM-MD5 PLAIN ETC
END

set sasl-step 0 0 [length]
data
STORED

get authenticated
[indicates done or STEP if SASL requires more steps]

... extra roundtrip in the protocol but this could be solved with
mget/mset.
