$parm = @{
    Description = @"
Loops all `$connections children
-Validates that is of the type EventHub, and is using the Managed Identity authentication scheme
--Creates a new resource in the ARM template, for the ApiConnection object
--With matching ARM Parameters, for the Namespace
--Makes sure the ARM Parameters logicAppLocation exists
--The type is based on the Managed Identity authentication
--Name & Displayname is extracted from the ConnectionName property
Requires an authenticated session, either Az.Accounts or az cli
