Suggested Solution - Settings for auto-fix - backend

This is a sub-issue for #216026 (closed)

We need to collect and save User preference for auto-fix solutions.

Implementation plan

• Create an API endpoint (Projects::Security::ConfigurationController#auto_fix) to toggle the new project setting Automatically create MRs for different report types.

POST namespace/project/-/security/configuration/auto_fix

params
{
  feature: String, ['container_scanning', 'dependency_scanning', 'all']
  enable: Boolean
}

• Those settings should be enabled by default.

Settings (ConfigurationPresenter#to_h) hash will include a new key:

{  
  "auto_fix_enabled": {
    "dependency_scanning": Boolean,
    "container_scanning": Boolean
  },
  "auto_fix_user_path": String
}
