handle errors with negative return code better

[rndmh3ro]

SUMMARY

In some cases the error returned by Grafana could have a status code -1, e.g.:

{'url': 'https://127.0.0.1:3000/api/users/lookup?loginOrEmail=username2', 'status': -1, 'msg': 'Request failed: <urlopen error [SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1007)>'}

or

{'url': 'https://127.0.0.1/api/users/lookup?loginOrEmail=username2', 'status': -1, 'msg': 'Request failed: <urlopen error [Errno 111] Connection refused>'}

This initial commit fixes the problem for the grafana_user module. However this could happen in all modules. Therefore we should refactor out the send_request function in all modules and fix it there..

test-case:

1. run grafana

> docker run -d -p 3000:3000 grafana/grafana:10.2.2

2. run the following playbook:

---
- hosts: localhost
  gather_facts: no
  vars:
    grafana_admin_user: grafana
    grafana_admin_password: grafana
    members:
      - uid: username
        description: 'User Name'
        email: '[email protected]'
        password: 'hashed_passwd'
      - uid: username2
        description: 'User Name1'
        email: '[email protected]'
        password: 'hashed_passwd'
  tasks:
    - name: Create Grafana users
      community.grafana.grafana_user:
        url: "https://127.0.0.1"        # ## notice this is wrong
        url_username: "{{ grafana_admin_user }}"
        url_password: "{{ grafana_admin_password }}"
        login: "{{ member.uid }}"
        email: "{{ member.email }}"
        name: "{{ member.description }}"
        password: "{{ member.password }}"
        state: "present"
      loop: "{{ members }}"
      loop_control:
        loop_var: member

result:

> ansible-playbook test2.yml
[WARNING]: No inventory was parsed, only implicit localhost is available
[WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit localhost does not match 'all'
