> 1. When we come on assign masters page we make 3 requests to recommendations
> API and 2 requests to validations API. But two requests are enough. Reduce 5
> requests to 2.
> 2. When user makes some changes on master assingments we send two requests:
> one for recommendations API and one for validations API. But we do not need
> recommendations as we already have that data.
> 3. Seems like list of sended components to validations is incorrect in some
> cases. On Add Service Wizard on Step5 we are sending information, that
> NodeManager is on c6403 host (1.png). But at the same time we don't have that
> component on c6403 host (2.png).
