This commit changes the
get_image_by_tagsand introduce a new optional argument namedrequired_tags, which when present will ensure thetagsparams must contain all of the required ones before searching for the AMI.The goal here is to prevent the use of
get_image_by_tagswithout important tags, causing the resulting image to be duplicated.Then, it changes the
publishmethod to ensure thesnapshot_tagsis always present when searching for image via tags, since we only consider the snapshot fully imported when this tag is added (see line 638):Without requiring the
snapshot_tagsto be present we may fall in a situation where the snapshot was not properly created and a bad result is returned, mainly leading to duplication of the AMIs for different image types.Refers to SPSTRAT-615
