Allow modification of "Create new Picture" product feature on a role.

[jvlcek]

Fixes https://bugzilla.redhat.com/show_bug.cgi?id=1727948

The ability to edit a role to enable the Create new Picture product feature was missing.
Prior to this PR the role associated with the user used to issue the Create new Picture
API call must have Everything enable for Product Features.

This PR adds that functionality under the API Product Features, as this functionality is
only available from the API.

Steps for Testing/QA [Optional]

Save the below script and set the image omitted due to size to be a valid image
in file, e.g.: /tmp/create_one_pictures.rb

#!/usr/bin/env ruby

# Jump past this huge data to the bottom of this source file

request_hash =
{
    "extension": "png",
    "content": "image omitted due to size"
}

require 'json'
require 'net/http'
require 'openssl'
require 'uri'

uri = URI.parse("https://#{ENV['MIQ']}/api/pictures")

http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
http.verify_mode = OpenSSL::SSL::VERIFY_NONE

request = Net::HTTP::Post.new(uri.request_uri)
request.basic_auth("new_user_2", "smartvm")
request.body = JSON.generate(request_hash)
response = http.request(request)
puts JSON.pretty_generate(JSON.parse(response.body.strip))

Create a new role in ManageIQ
Edit the role and uncheck the Everything box
Click all other boxes next to all other product features, making sure the new
API/Pictures/Create new Picture Product Feature is checked.

Create a new group with the new role create above
Create a new user named, for example, new_user_2

Run the following shell commands on a separate system, e.g.
a laptop on the same network as the ManageIQ appliance:

export MIQ="IP Address to the test MangeIQ appliance"
chmod a+x /tmp/create_one_pictures.rb
/tmp/create_one_pictures.rb

Confirm the new picture was create on the appliance
