> h2. Description of the problem
> When retrieving a large number of resources which have tags associated with, retrieval
methods took too long. Our goal is to improve performance of this methods avoiding query the
database for each tag, managing that information in memory.
> API methods to improve: {{listTemplates}}, {{listVolumes}}, {{listVirtualMachines}}
> To achive it, it's necessary to include new columns in {{template_view}}, {{volume_view}}
and {{user_vm_view}}:
> * tag_account_name
> * tag_domain_name
> * tag_domain_uuid
