GEODE-3520: isValid API made public

        * In case an index update corrupts the index, the index will be marked 
invalid
        * Queries will not use that index while executing queries.
        * The API isValid had been made public so that users can find out if 
the index ia valid or not
        * A new field has been added to the list index gfsh command which shows 
the isValid flag.
        * If while loading the data index during its creation and it causes an 
exception, the index creation will fail.


> IndexMaintenanceExceptions should not affect a put

> If during index maintenance i.e. index update during a put operation , if 
> there is an exception, the index is marked invalid, however the put will be 
> successful as it is present in the data regions.
> This will require us to provide a user a way to determine which indexes are 
> valid/invalid (maybe a new column in GFSH to describe index).  The query 
> engine would need to avoid using indexes marked as invalid.
> Also provide a Java API isValid on the indexes to know if they are valid.
