> While adding a host, on hitting next button on Assign slaves and clients page
> validation issues are prompted by the recommendation/validation API. This
> logic on the FE needs to be intercepted to make an exception for any
> slave/client component that has cardinality of "All".
> If a slave/client component has the cardinality "All" then the validation
> error thrown should not be shown to the end user on Assign slaves and clients
> page as UI on hitting next on "Review page" explicitly creates the
> hostcomponent on all hosts of the cluster for the components that has
> cardinality "All".
