Can you just push this log message into intRequirement? No reason for it to return an error if we're not going to do anything with it - plus then the default is only being set in one place.

```
func intRequirement(key string, jr map[string][]string, defaultValue int) (int)

spec.MemoryRequired = intRequirement(job.FleetXMemoryRequired, jobRequirements, defaultMemoryRequired)
spec.CoresRequired = intRequirement(job.FleetXCoresRequired, jobRequirements, defaultCoresRequired)
...
```
