DHCP smart proxy implementation does not honor configured omapi port for ISC dhcpd
The current ISC DHCP smart proxy implementation (and docs +) references the omapi-port (default 7911), but does not actually read this setting from dhcpd.conf.
A call to omshell from smart-proxy/modules/dhcp/providers/server/isc.rb is therefore falling back to the default port 7911.
I prepared a simple fix (needs further testing) and do think it might also be helpful to add this default to the configuration example. Pull request currently in the works.
