Constructs a Page based on the given content, Pageable and Supplier applying optimizations. The construction of Page omits a count query if the total can be determined based on the result size and Pageable. 
Params:
content – must not be null.
pageable – must not be null.
totalSupplier – must not be null.
Returns:
the Page./**
