描述
#### Bug, feature request, or proposal:
feature request
#### What is the expected behavior?
Have a constructor that, at least optionally, takes a MatSort and/or a MatPaginator as parameters.
#### What is the current behavior?
Currently, you have to create a new MatTableDataSource with only data as a parameter. However, you always have to set the matSort and paginator of the MatTableDataSource after construction. I had to make a class that extends this class to have this, which seems superfluous.
#### What are the steps to reproduce?
#### What is the use-case or motivation for changing an existing behavior?
To make the creation of MatTableDataSources easier.
#### Which versions of Angular, Material, OS, TypeScript, browsers are affected?
Angular: 5.0.1
Material: 5.0.0-rc0
OS: Windows 10 Pro
TypeScript: 2.6.1
Browser: Google Chrome 62.0.3202.94 (Official Build) (64-bit)
#### Is there anything else we should know?

调研方向
首先定位 MatTableDataSource 的入口点及其现有测试,然后检查 MatSort 和 MatPaginator 在构造后目前是如何分配的。完成的标准是构造函数可选地接受这些对象,并且测试覆盖使用每种受支持组合进行构造的情况。
