Add Fitbit provider

[jerriep]

@jmloeffler Indicated he will pick this one up

[jmloeffler]

Yep, I am working on it. I've got it working already but want to spend a little more time testing and ran out of hours in the day.

[jerriep]

No problem. I just tagged you to make sure no-one else picks it up.

Take your time with getting it done :)

[jmloeffler]

I've noticed that we've got values in the providers for the clientid and secret in the Startup.cs of the sample app. Are those legit values? I would normally leave these blank and comment out the section so the provider isn't active until someone provides values.

They were legit at the time of merging the PR so that @PinpointTownes could easily test, since he did not have to go and create an app just to test. I deleted mine in the meantime, and you should do the same.

But it is not a very good practice to leave those in. We should come up with something else. The important thing is that @PinpointTownes must be easily able to test PRs

@jerriep I totally agree 👍

FYI: I already removed all the app.Use*Authentication calls (except GitHub/Twitter/Google) from the MVC sample since they were no longer working.
