feature request - gitlab_project_external_status_check resource

New Resource

I'm looking for something that I could use like this:

resource "gitlab_project_external_status_check" "status_check" {
    project              = 123456
    name                 = "important status check"
    external_url         = "https://external-url.example.com"
    shared_secret        = <secret contents>
    protected_branch_ids = [1, 2, 3]
}

API documentation: https://docs.gitlab.com/api/status_checks/

Additional Details

• GitLab REST API resources available (read for data sources, CRUD for resources)
• client-go supports the related GitLab API already
• I'd like to contribute it myself
