    Is it possible to re-use a generic Value::Scalar input validator instead of 
defining inline?

    Maybe also check isnormal?

Lines 340 (patched)
<https://reviews.apache.org/r/70161/#comment299541>

    Can we include in the error string which guarantee is invalid?



src/master/quota.cpp
Lines 348 (patched)
<https://reviews.apache.org/r/70161/#comment299542>

    Ditto here for which limit is invalid?



src/master/quota.cpp
Lines 352-366 (patched)
<https://reviews.apache.org/r/70161/#comment299543>

    Could this be written as:
    
    ```
    ResourceLimits limits = x;
    ResourceQuantities guarantee = y;
    
    if (!limits.contains(guarantee)) {
      // error
    }
    ```
    
    That way, we could consider just unit testing one contains issue for this 
function and rely on the .contains test for being more comprehensive?
