Feature #679 - create initial channel when creating app (#708)

* Added bindle-client dll to the infrastructure

* Added bindle client interface to application and implementation to core

* added bindle service to dependency injection and instantiated the BindleClient

* Added configuration as DI, fixing mistake from past commit

* removed dll, added package reference

* Create initial channel when app created

* Integrate bindle-dotnet in project infrastructure

* Removed local dll reference

* Make sure domain name is valid for initial channel
