Make AWS attach/detach operations faster

Most attach/detach operations on AWS finish within 1-4seconds.
By using a shorter time interval and higher exponetial
factor  we can shorten time taken for attach and detach to complete. 

After this change retry interval looks like:

```
[1, 1.8, 3.24, 5.832000000000001, 10.4976]
```

Before it was:
```
[10, 12.0, 14.399999999999999, 17.279999999999998]
```
