917639 - cli - fix changeset update add_repo command

It appears tha the ordering of the arguments to add_repo
may have been altered during a merge.  This fixes it so that
the user may now execute the following:

changeset update --from_product product --add_repo "repo 1"
   --org ACME_Corporation --name cs --environment dev
917608 - cli - fix activation key update

Prior to this commit user would get error similar to :
   error: local variable 'view' referenced before assignment

when executing command like:
   activation_key update --org ACME_Corporation --name key1 --limit 2
