* Backoff from Scan2 which is experimental to legacy pagination API call
This commit rewrite simplifiedGitlabEnumeration to use legacy pagination API call with keyset pagination instead of Scan2 which is currently in experimental state. Note
that this doesn't promise to fix this problem it's just a test to check. It also adds a retry logic in case any 500 error occurs. I added some logs as well to keep track
of no of projects being enumerated.
* implemented builtin retry mechanism for gitlab and proper handling of next page
* fixed basic auth
* Some enhancements
Reversed the gitlab cloud logic to add membership flag, so that we use the default false for non gitlab.com instances.
This can help if the issue really was membership flag as mentioned in some gitlab issues.
Also added simple flag in list projects to get only minimal fields in response instead of big json response for each project.
Added test case as well.
* enhance the test case
