Change hardcoded ports in firewalld.yml file

[JensMKofoed]

Hi,

Many thanks for a wonderful role for installing and configure zookeeper. It saves my hours to write my own.
A suggestions is to change the hardcoded ports in the firewalld.yml file:
From:
name: Add firewalld rules
firewalld:
port: "{{ item }}"
permanent: yes
state: enabled
loop:
- 2181/tcp
- 2888/tcp
- 3888/tcp
notify: Reload firewalld

To:
name: Add firewalld rules
firewalld:
port: "{{ item }}"
permanent: yes
state: enabled
with_items:
- "{{ (zookeeper_client_port }}/tcp"
- "{{ zookeeper_leader_port }}/tcp"
- "{{ zookeeper_election_port }}/tcp"
notify: Reload firewalld

Kind regards
Jens M. Kofoed
