Application routing now uses SecureComponent and hasPermission function (#1288)

- Some menu options were not showing even if the user has access to
  perform the operations (IAM Policies)
- Deleted unecessary backend endpoints.go logic, instead using
  SecureComponent to validate application routes and Menu options
  rendering
- All the logic related to routes and permissions is now in the
  permissions.ts file
- Added SecureComponent to List Users page
- Separated Menu options and routing logic for AdminConsole and
  OperatorConsole
- Tools are hidden if user don't have access to them or MinIO is running
  in fs mode (heal, audit log, etc
- Hide change-password button if user don't have access
- Hide create user button if user don't have access
- fixed some bugs when ldap/oidc is enabled
