[pdm-devel] [PATCH datacenter-manager] fix #7120: remote updates: drop vanished nodes/remotes from cache file

[Lukas Wagner]

This commits makes sure that vanished remotes and remote cluster nodes
are dropped from the remote updates cache file. This happens whenever
the cache file is fully refreshed, either by the periodic update task,
or by pressing "Refresh All" in the UI.
