This patch refactors gun pooling to use Elixir process registry and simplifies adapter option insertion. Having the pool use process registry instead of a GenServer has a number of advantages: - Simpler code: the initial implementation adds about half the lines of code it deletes - Concurrency: unlike a GenServer, ETS-based registry can handle multiple checkout/checkin requests at the same time - Precise and easy idle connection clousure: current proposal for closing idle connections in the GenServer-based pool needs to filter through all connections once a minute and compare their last active time with closing time. With Elixir process registry this can be done by just using `Process.send_after`/`Process.cancel_timer` in the worker process. - Lower memory footprint: In my tests `gun-memory-leak` branch uses about 290mb on peak load (250 connections) and 235mb on idle (5-10 connections). Registry-based pool uses 210mb on idle and 240mb on peak load
