Problem:
On an existing host, try to change the PXE Loader from the Foreman web UI. Results in error
Create DHCP Settings for lucia-noice.helab.in task failed with the following error: ERF12-6899 [ProxyAPI::ProxyException]: Unable to set DHCP entry ([RestClient::Conflict]: 409 Conflict) for proxy https://thepuppetmaster.helab.in:8443/dhcp
However the dhcp lease file gets updated with the new entry.
Expected outcome:
DHCP lease file will already have an entry for this host. On changing the PXE Loader, it should invalidate this entry an write a new entry at the bottom.
