CLOUDSTACK-9594: API "list templates templatefilter=all" reveals all
API "list templates templatefilter=all" reveals all templates.
Using a "list templates templatefilter=all" API call any domain admin can
see all templates of all domains in ACS. Information returned includes the
account and domain of the template's owner.
The template data shows what that VM is using and any hints from the label.
This would give an advantage in what attack vectors to use. The account and
domain can possibly be used in brute force attack to guess the password and
login information.
Test Scenario:
created two accounts in different domain.

Bug has been fixed considering below points
1. templatefilter=all or isofilter=all is applicable only to admin and
domain admin.
2. With templatefilter=all or isofilter=all below are the visiblity of
templates in system.
- admin should be able to see all templates/iso in system.
- domain admin should be able to see all public template and templates
under its domain tree (including sub domain).
- domain admin in a project context should be able to see all public
templates and templates registered
as project account and templates which are shared(using
updateTemplatePermission api) with project account.

This marvin test was written for this scenario but for the second account
"templatefilter=all" is not used.
