Handling concurrency

Currently Adelnor allows to run the server using different concurrency strategies, one at a time.

require './lib/adelnor/server'

app = -> (env) do
  [200, { 'Content-Type' => 'text/html' }, 'Hello world!']
end

# Threaded mode
Adelnor::Server.run app, 3000, thread_pool: 5

# Clusterd mode (forking)
Adelnor::Server.run app, 3000, workers: 2

# Async mode
Adelnor::Server.run app, 3000, async: true
