Convert config to content entities

we have some mess here with 2 MRs for single issue

this should be fixed to have only 1 branch with proper changes

mmm I got updated all locally(MR7 and MR8) however I can't use the MR7. @sorlov.

Can you explain how you got this MR locally?

The following, as usual, doesn't work:

git remote add http_status_code-3250508 git@git.drupal.org:issue/http_status_code-3250508.git
git fetch http_status_code-3250508
git checkout -b '8.x-1.x' --track http_status_code-3250508/'8.x-1.x'
fatal: A branch named '8.x-1.x' already exists.

Moved all changes from MR7 to MR8, so MR7 can be closed not (don't have enough permissions on my side to do that)

so MR8 can be reviewed now
