Incorrect example for icinga2::object::apiuser

[mphilipps]

hi
icinga2::object::apiuser expects an array of strings or hashes for it's permission argument. The example

permissions = [
  {
    permission = "objects/query/Host"
    filter = {{ regex("^Linux", host.vars.os) }}
  },
  {
    permission = "objects/query/Service"
    filter = {{ regex("^Linux", service.vars.os) }}
  }
]

does neither and as such doesn't work.
I suggest changing it to:

permissions => [
  {
      permission => "objects/query/Host"
    , filter => "{{ regex(\"^Linux\", host.vars.os) }}"
  },
  {
      permission => "objects/query/Service"
    , filter => "{{ regex(\"^Linux\", service.vars.os) }}"
  }
]
