> {{LIKE}} predicates can only be used with the SASI indices. In several 
> usecases (e.g. querying the {{settings}} virtual table) it makes sense to 
> support them for filtering.
> +Additional information for newcomers:+
> There are some checks in the {{StatementRestrictions}} constructor and on 
> {{LikeRestriction}} that need to be removed for allowing filtering using LIKE 
> on clustering and regular columns.
> For filtering on partition columns the {{needFiltering}} methods in 
> {{PartitionKeySingleRestrictionSet}} will need to be modified to return true 
> when LIKE predicate are used.
> The unit tests should go in {{SelectTest}}.
