Change Semaphore contract

[tshemsedinov]

Now:

const CONCURRENCY = 3;
const QUEUE_SIZE = 4;
const TIMEOUT = 1500;
const semaphore = new Semaphore(CONCURRENCY, QUEUE_SIZE, TIMEOUT);

After change:

const options = { concurrency: 3, size: 4, timeout: 1500 };
const semaphore = new Semaphore(options);
