# Fact: dhcp_servers
#
# Purpose:
#   Return the DHCP server addresses for all interfaces as a hash.
#   If the interface that is the default gateway is dhcp assigned, there
#   will also be a 'system' entry in the hash.
#
# Resolution:
#   Parses the output of nmcli to find the DHCP server for the interface if available
#
# Caveats:
#   Requires nmcli to be available and the interface must use network-manager.
#
