feat(datepicker): add suppression of validation for #3836

[Blackbaud-PatrickOFriel]

This adds the $datepickerSuppressError value provider which has an isSuppressed property to allow the option to suppress the $log error in DatepickerController. This was made to address #3836

Just make it a boolean - no need for an object here.

Just make all changes related to my comment and this PR should be good to get in.

The only reason I made it an object is because when it's a literal, changes you make upon injection don't take effect (setting $datepickerSuppressError to true). You could only change the value in the config phase using $provide. If that's the route I should take, then I'll have to make the test a bit different since you can't use $provide after you've used inject.

I think that is fine - there really isn't a great use case for toggling suppression on or off once the app is running.

[Blackbaud-PatrickOFriel]

Okay I'll go ahead and make the change then

[Blackbaud-PatrickOFriel]

So in order to test properly I had to wrap the other tests in their own describe block so that I could override the $provide for my test cases before the inject function was ever called. And now the diff tool makes it look like I deleted everything and added it back...

[wesleycho]

That's perfectly fine

Can you squash your commits into one?

[Blackbaud-PatrickOFriel]

Squash complete

LGTM - merging shortly. Thanks for the work!

[Blackbaud-PatrickOFriel]

No problem! Thanks for this entire library, it's great!
