Description of problem:

Trying to issue a concurrent location creation (through Ansible, in our case) for 1 Satellite and n capsules creates n+1 locations with the same name instead of 1 and returning 422 for the rest of them

Version-Release number of selected component (if applicable):

I've tested this in 6.13 and Stream, so I suppose that all the versions in between are also affected.

How reproducible:

Always.

Steps to Reproduce:
1. Create the equivalent of this Ansible playbook:

```

• name: "Create location(s)"
  ansible.builtin.uri:
  url: "https://{{ satellite }}/api/locations"
  method: POST
  user: "admin"
  password: "{{ pass }}"
  force_basic_auth: True
  validate_certs: False
  body: "{{
  Unknown macro: { 'location'}

  }}"
  status_code:

• 201
• 422 # "Name has already been taken"
  body_format: json
  ```

2. Run the playbook against a bunch of systems using a new location as parameter (the same for every system).

3. Check the number of locations created.

Actual results:

n+1 new locations are created, all with the same name and characteristics.

Expected results:

Only 1 location is created and a 422 status is reported for the rest of them.
