WebUI: add vault management
    
    Add vault management into WebUI, there are some constraints:
    - There is no crypto library so Symmetric and Assymetric vaults
      are not supported in WebUI. Also retrieving or archiving data
      is not supported.
    - There aren't any container support right now
    
    Supported is:
    - Browsing vaults
    - Adding Standard vaults (users, service, shared)
    - Removing vaults
    - Adding and removing owners
    - Adding and removing members
