Description of problem:

When calling the api/registration_commands endpoint to generate the host registration command like:

curl -X POST https://xxx.xxx.redhat.com/api/registration_commands \
--user "admin" \
-H 'Content-Type: application/json' \
-d '{ "registration_command": { "activation_keys": ["test-ak "], "location_id": 4, "organization_id": 1 }}'

below curl command is generated:

curl -sS  'https://xxx.xxx.com/register?activation_keys=test-ak+\u0026location_id=4\u0026organization_id=2' -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjo0LCJpYXQiOjE2ODkyMjMxNjUsImp0aSI6ImYzMmU1OTg3OThjMzM4YzAwMTBiNDE2NmUxMzJhMjZjZTkzMDIzZjdmYjY0MGVlOTI0MTcyNzgyYjg5NGY1M2IiLCJleHAiOjE2ODkyMzc1NjUsInNjb3BlIjoicmVnaXN0cmF0aW9uI2dsb2JhbCByZWdpc3RyYXRpb24jaG9zdCJ9.0nKQrYqCKSW4O_nohmB4SsquNSuQzd4N4WNuwiJAFBc'

as you can see, \u0026 is there rather &.  The result of running the curl command is that location_id and organization_id are not passed to the global registration template:

~~~
#!/bin/sh

# Make sure, all command output can be parsed (e.g. from subscription-manager)
export LC_ALL=C LANG=C
....
register_host() {
  curl --silent --show-error --cacert $SSL_CA_CERT --request POST https://xx.xxx.redhat.com/register \
       -H 'Authorization: Bearer eyJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjo0LCJpYXQiOjE2ODkyMjM1NzEsImp0aSI6ImJjMGQyZWM1MGEwZjEwMDc3ZTAxMmQ3ZjgwY2JhOTJhNDE4MDAxMjcwNTA2YjNiYmM3ZGRjYTUwOGNmZGVkOTMiLCJleHAiOjE2ODkyMzc5NzEsInNjb3BlIjoicmVnaXN0cmF0aW9uI2dsb2JhbCByZWdpc3RyYXRpb24jaG9zdCJ9.4UvxwfsvpyTMqZiihLu0R6rLft1-3z1z_p1uQJLnQ8o' \
       --data "host[name]=$(hostname --fqdn)" \
       --data "host[build]=false" \
       --data "host[managed]=false" \
       --data 'host[organization_id]=1' \  <== should be 2 
       --data 'host[location_id]=2' \ <== should be 4

}
