External version of module

This version allow for adding server thumbprint on tentacles and leaving tentacles unmanaged until manually registered on the server. Used to address a single use-case. Expected to be addressed by the main version in the future.
Usage:

    cTentacleAgent OctopusTentacle 
    { 
        Ensure = "Present" 
        State  = "Started" 
        Name   = "Tentacle"           
        AutoRegister = $false
        OctopusServerThumbprint = '<server_thumbprint>'
        ListenPort                  = 10933
        DefaultApplicationDirectory = "C:\Applications"
        OctopusHomeDirectory        = "C:\Octopus"
    }
