Description of problem:
when provisioning a new host, in the interfaces section, when is tried to configure a new interface on a sat6 with an external dhcp integration enabled, you obtain an error:
Failed to fetch a free IP from Capsule %{Capsule}: %{message}
In addition to the fact that in the UI %{Capsule} and %{message} are not substituted, the core of the problem under the hood is that instead of an IP, is returned:
undefined method `to_i' for [["9000"]]:Array (NoMethodError)
this bug is blocker because it prevent from using the provisionig mechanism of Sat6 after updating, while on 6.3.4 was correctly working
Version-Release number of selected component (if applicable):
foreman-proxy-1.18.0.1-1.el7sat.noarch
How reproducible:
Always
Steps to Reproduce:
1. Setup an external DHCP
2. Configure Sat6 to make use of dhcp via capsule
3. Setup a subnet to be managed by that capsule
4. curl -RLv --cacert /etc/foreman-proxy/foreman_ssl_ca.pem --key /etc/foreman-proxy/foreman_ssl_key.pem --cert /etc/foreme: application/json" https://sat6.home.local:9090/dhcp/192.168.2.0/unused_ip?from=192.168.2.150

Expected results:
To receive a free ip from the pool
Additional info:
Verified fix in Sat 6.6 snap 12
1. Created dhcpd.conf with 'option interface-mtu 3000;' in subnet
2. Configured satellite with 'satellite-installer --foreman-proxy-plugin-dhcp-remote-isc-dhcp-config'
3. Imported subnet into satellite.
4. Used subnet to provision host.
The host was assigned a IP address as expected.
