Description of problem:
POST, PUT and DELETE calls fail with "Unable to authenticate user" when using kerberos authentication. At the same time, GET calls pass without any issues.

Version-Release number of selected component (if applicable):
6.12.0 snap 8

How reproducible:

Steps to Reproduce:
1. Have a Satellite configured for Kerberos authentication.
2. Run kinit <someuser> to get ticket.
3. Call /extlogin to get session_id and store it in a cookie file:
  1. curl -k -c cookies.txt -u : --negotiate
    4. Using the cookie file try GET call to some endpoint, it works:
  2. curl -b cookies.txt -H "Accept:application/json,version=2" -H "Content-Type:application/json" -X GET -k
    5. Using the same cookie file try POST/PUT/DELETE call to create/update/delete an entity:
  3. curl -b cookies.txt -H "Accept:application/json,version=2" -H "Content-Type:application/json" -X POST -d '{"name":"8051"}' -k

Actual results:

It fails with this response: {
"error": {"message":"Unable to authenticate user "}

In the production log we can see:

Fixes #35473 - Add extlogin API endpoint

/users/extlogin endpoint is designed for UI interaction, thus
using this endpoint to create a session to be used via API will
fail with "Can't verify CSRF token authenticity" for any method
except GET. We need to have a separate endpoint to create a proper
session to be used via API.
