$parm = @{
    Description = @"
Loops all `$connections children
-Validates that is of the type EventHub, and that is using the classic connection string approach
--Creates a new resource in the ARM template, for the ApiConnection object
--With matching ARM Parameters, for the connection string as a Secure String
--Makes sure the ARM Parameters logicAppLocation exists
--The type is based on ConnectionString approach
--Displayname is extracted from the Api Connection Object
--The displayname will be configured to be the same as the name of the connection
Requires an authenticated session, either Az.Accounts or az cli
