Usage

default_port: 1234
params: ['params', 'of', 'things']
connection: 'ansible_ssh_host'
servers: '{{ groups['group_of_servers'] | format_haproxy_servers(default_port, params, connection) }}

This will return a list of servers like this

... [{'name': name, 'ip': ip_address, 'params': ['params', 'of', 'things']}]
