For the AutocompleteFormat function we expect the correct template struct which is used in the golang template. The function can handle both struct and pointer to a struct. Using the reference is more efficient since it doe snot have to copy the whole struct. Also change some structs to use he actual type from the template instead of some nested one to make sure it has to correct fields. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
