Add CloudWatchEvent rule name and description fields

[horike37]

What did you implement:

Closes #2832

How did you implement it:

It is possible to add name and description property of scheduled event in CloudFormation.
These are not required properties.

How can we verify it:

set property as follow

      - schedule:
          name: my-scheduled-event
          description: 'my scheduled event'
          rate: rate(10 minutes)

deployed name and description to a scheduled event Lambda

@horike37 thanks for this PR! 👍

Tested it locally and it worked like a charm!
I just merged the current master into this one so that we can get rid of the failing linting test.

GTM from my side!

I think it's better to leave existing examples as they are and add another one with name and description.
