New Powershell cmdet to Create Connection Types
Connection types are defined as a file in the module file. Is there a reason that you want to created them via cmdlets instead?
As a side note, you can do this through our API today as a workaround.

It would be nice to have a way to create a connection type from Powershell without the need to upload a module, if users have not seen the blog post on how to create a connection type, when they look through the powershell cmdlets they will find a way to create the connection type.
