[pdm-devel] [PATCH datacenter-manager v2 3/4] ui: widget: add remote endpoint selector

[Dominik Csapak <d.csapak@proxmox.com>]

this is a widget to select a specific endpoint, showing the hostname as
the value. This can be useful in situations where we wan to explicitly
select an endpoint, e.g. remote migration.
