Broken on RedHat

[rohit-gohri]

Describe the bug

• Adding repo fails because it is missing become: yes
  

  ansible-telegraf/tasks/RedHat.yml

  Lines 16 to 24 in 8fdab6f

  	- name: "RedHat | Add yum repository"
  	yum_repository:
  	name: influxdb
  	description: InfluxDB Repository - RHEL $releasever
  	baseurl: "{{ telegraf_yum_baseurl[ansible_distribution|lower] | default(telegraf_yum_baseurl['default']) }}"
  	gpgcheck: yes
  	gpgkey: https://repos.influxdata.com/influxdb.key
  	when:
  	- telegraf_agent_package_method == "repo"

• This throws a syntax error
  

  ansible-telegraf/tasks/RedHat.yml

  Lines 32 to 33 in 8fdab6f

  	http_proxy: "{{ http_proxy | default(None) | omit }}"
  	https_proxy: "{{ https_proxy | default(None) | omit }}"

  
  I think should be default(omit) after looking at Debian.yml
