event name checks

[mpechner-akasa]

For lambda, I know it has not change often at all, but instead of looking for 'DeleteFunction20150331' and 'TagResource20170331v2' why not just test for starts with "DeleteFunction" and "TagResource"

Looking at: https://gist.github.com/pkazi/8b5a1374771f6efa5d55b92d8835718c

There are/have been 3 values: TagResource TagResource20170331 TagResource20170331v2
