PlugLimit - rate limiting Plug module based on Redis Lua scripting

PlugLimit is using Redis Lua scripting to provide rate-limiting functionality for web applications based on a Plug library. Salient Redis Lua scripting feature is a race conditions resiliency which makes it a recommended solution for distributed systems (e.g.: Phoenix servers swarm behind a round robin load-balancer).

PlugLimit provides two built-in rate limiters: fixed window and token bucket. Custom rate limiters can easily be added as a user defined Redis Lua scripts.

Not diminishing your work, just want to point out an alternative library for future readers, maybe even for you to draw some inspiration from: GitHub - ExHammer/hammer: An Elixir rate-limiter with pluggable backends

Thanks for your work and for publishing it!
