cast grafana_port to int before comparing it to 1024

[kapouer]

What happened?

The conditional check 'grafana_port <= 1024' failed.
The error was: Unexpected templating type error occurred on ({% if grafana_port <= 1024 %} True {% else %} False {% endif %}): '<=' not supported between instances of 'str' and 'int'
The error appears to be in '/home/dev/.ansible/roles/cloudalchemy.grafana/tasks/preflight.yml': line 80

Did you expect to see some different?
grafana_port should be settable using jinja templates.

How to reproduce it (as minimally and precisely as possible):

• set_fact: myport=9999
  ...
  grafana_port: "{{ myport }}"

Environment
debian/sid

• Role version:
  0.16.2

• Ansible version information:
  2.9.6

• What else ? *

I tried to use the | int filter but it won't work. "Jinja always output strings".

Probably needs altering this line: https://github.com/cloudalchemy/ansible-grafana/blob/master/templates/grafana.ini.j2#L20 Could you create a PR and test it?

[kapouer]

No that won't work: the check is in a task, not in a template.

But let me PR this another way
