    Confused by this one. Don't we have three cases?
    
    * Neither property set. No SSL.
    * Both properties set, use SSL.
    * Incorrectly set, exception, this object is not created.
    
    So `isValid` in the sense of "is the data valid" is unnecessary: the object 
is not created if invalid. But, "isSslEnabled" is useful. Rather than exposing 
a member variable, perhaps expose a function `isSslEnabled()`.


> Drillbit fails to start when only keystore path is provided without keystore 
> password.

> When we configure keystore path without keystore password inside 
> drill-override.conf for WebServer, then Drillbit fails to start. We should 
> explicitly check for either both being present or both being absent. If any 
> one of them is only present then throw startup exception for Drill.
