The semaphore resiliency pattern for golang.

Creating a semaphore takes two parameters:
- ticket count (how many tickets to give out at once)
- timeout (how long to wait for a ticket if none are currently available)

```go
sem := semaphore.New(3, 1*time.Second)

if err := sem.Acquire(); err != nil {
	// could not acquire semaphore
	return err
}
defer sem.Release()
```
