Current behavior

Angular2 DatePipe does not support ordinal indicators (1st, 2nd, 5th etc)

Expected behavior

Ideally there would be a format option for the ordinal indicator proceeding the date number.

eg. {{ myDate| date: 'dO' }} where O would be the ordinal indicator.

Minimal reproduction of the problem with instructions

N/A

What is the motivation / use case for changing the behavior?

I am listing a bunch of a events that have their respective dates displayed. In our design, each date is in the following format "22nd September"
