[UI] Customize proxy replicas and resources during DB creation in the wizard

Similarly to the way that users are able to customize the number of DB engine replicas and resources they should also be allowed to customize the number of proxy replicas and their resources (CPU and RAM).

During that setup, the number of proxy replicas should follow the number of nodes, unless the user manually changes that number.

Changing a selected preset in the nodes mustn’t change the preset in the proxies.
