fix: remove CloudFormation property renames (#973)
Browse files Browse the repository at this point in the history
The construct id parameter used to be a property called `name` in the 
props object, and so properties called `name` were renamed to `xxxName`
(where `xxx` is the name of the resource). Since we now pass names as
a constructor argument, we can get rid of the properly rename mechanism.

BREAKING CHANGE: if you use L1s, you may need to change some
`XxxName` properties back into `Name`. These will match the CloudFormation
property names.

Fixes #852.
