[tor-commits] [ooni-probe/master] Add NetTestCase option validation

[isis@xxxxxxxxxxxxxx]

commit 54d2aa3fb57f733ab9285df2eab685fa2e0e12fe
Author: aagbsn <aagbsn@xxxxxxxx>

    Add NetTestCase option validation
    
    Options that are passed to the NetTest constructor must be valid
    options defined in the NetTestCase UsageOptions with optParameters.
    
    Also handle the case where inputFile is *not* a required option and not
    supplied gracefully.
