fix(cli): update bit.ly link to be directly to github

[alsmola]

The http://bit.ly link seems suspicious. At least make it https, or better yet link directly to the issue.

Update http://bit.ly/cdk-2EhF7Np => #1299

I agree, it's more transparent and clean to get this link updated.

I think this is making the CLI Integration test fail. The change was made in the test but doesn't seem to be in CDK

aws-cdk/packages/@aws-cdk/cloudformation-diff/lib/format.ts

Line 69 in f827a88

formatter.warning(`(NOTE: There may be security-related changes not in this list. See http://bit.ly/cdk-2EhF7Np)`);
