improve debug information in actions errors response (close ) ()
* config options for internal errors for non-admin role, close 

More detailed action debug info is added in response 'internal' field

* add docs

* update CHANGELOG.md

* set admin graphql errors option in ci tests, minor changes to docs

* fix tests

Don't use any auth for sync actions error tests. The request body
changes based on auth type in session_variables (x-hasura-auth-mode)

* Apply suggestions from code review

Co-Authored-By: Marion Schleifer <marion@hasura.io>

* use a new sum type to represent the inclusion of internal errors

As suggested in review by @0x777
-> Move around few modules in to specific API folder
-> Saperate types from Init.hs

* fix tests

Don't use any auth for sync actions error tests. The request body
changes based on auth type in session_variables (x-hasura-auth-mode)

* move 'HttpResponse' to 'Hasura.HTTP' module

* update change log with breaking change warning

* Update CHANGELOG.md
