Fix zuul config for heat-functional
Fix zuul config for heat-functional

YAML indentation is wrong, instead of their appropriate sections
options are set to the DEFAULT section of config like the following

  [DEFAULT]
  heat_api = {'workers': 2}

not sure if oslo.config handles that properly so better fix this.
