Issue:
FormControlLabel should offer typography options
FormControlLabel offers no option to customize the typography variant. 

https://github.com/mui-org/material-ui/blob/master/packages/material-ui/src/FormControlLabel/FormControlLabel.js#L104

- [x] I have searched the [issues](https://github.com/mui-org/material-ui/issues) of this repository and believe that this is not a duplicate.

## Summary 💡

I would suggest FormControlLabel should accept the following additional properties:

 + disableTypography
    + this will allow people to pass in their own typography element and it will still recieve the benefits of the "checked" css (which only affects the first level component)
+ labelTypographyProps
    + in the style of ListItemText, these props would be spread to the typography element for customization


## Examples 🌈

similar setup in ListItemText

https://github.com/mui-org/material-ui/blob/master/packages/material-ui/src/ListItemText/ListItemText.js#L56

## Motivation 🔦

We use material-ui as a basis for our own component library. so although we use Typography, we use it with restricted options and / or an altered typography set. In the perfect world, we will use `disableTypography` and pass 
(<Typography variant="body2">{label}/Typography>) in order to follow our own guidelines. It seemed odd that there were no options in this component compared to others



Discussion:
We have faced a similar problem in the past. So far (in the history of the project), we have used 4 options:

1. Nesting of two typography, one from the component, another from the developer. 
2. Disabled prop https://github.com/mui-org/material-ui/blob/018118626718d2f4c86212699912700682d80956/packages/material-ui/src/DialogTitle/DialogTitle.js#L56
3. Autodisable https://github.com/mui-org/material-ui/blob/018118626718d2f4c86212699912700682d80956/packages/material-ui/src/ListItemText/ListItemText.js#L94
4. Spread of extra props https://github.com/mui-org/material-ui/blob/018118626718d2f4c86212699912700682d80956/packages/material-ui/src/ListItemText/ListItemText.js#L101
