use LUA to increase and expire keys safely

[tbarbugli]

fixes #14

[tbarbugli]

any chance to see this merged or addressed? the bug addressed here is quite critical as the rate limiter can "leak" keys and give false positive until the key is manually evicted.

More information about this. I am now tracking how many keys are in redis without a set TTL.

redis-cli -h ip.address.of.redis -n 8 info | grep db8 | awk 'BEGIN { FPAT="[0-9]+"} { if ($2 != $3) { print "some keys in Redis rate limiter have no TTL"; exit 1 } }'

I am running this every couple of minutes and I see the script "failing" once or twice a day. As I said before this is a big issue.

Fork this library into your own namespace and install it on your environment like this
pip install git+https://github.com/tbarbugli/limits.git

@thestick613 I know how to install packages from git. I rather see bugs getting fixed on the upstream library and stick with that ;)

@tbarbugli sorry for the delay. could you rebase your branch? Also, why the forced version?
