ResourceKeys (Slider Core 0.90.2-incubating API)

```
public interface ResourceKeys
```
These are the keys valid in resource options /* Container failure window. The window is calculated in minutes as as (days * 24 *60 + hours* 24 + minutes) Every interval of this period after the AM is started/restarted becomes the time period in which the CONTAINER_FAILURE_THRESHOLD value is calculated. After the window limit is reached, the failure counts are reset. This is not a sliding window/moving average policy, simply a rule such as "every six hours the failure count is reset"
