Tacker CLI does not support updating name and description of VIM.
This patch introduces --name and --description options to vim-update.
Also, existing --is-default option's behavior can be improved.
Currently is_default attribute will be set to False when --is-default
is ommited, and will be set to True when --is-default is specified.
So even a user, who wants to update attributes other than is_default,
needs to be aware of current is_default setting. This patch will make
the behavior of --is-default option clearer like below:
1.When --is-default True is specified, it'll be set to True.
2.When --is-default False is specified, it'll be set to False.
3.When --is-default is ommited, it will stay as-is.
In addition, --config-file should be a required option because both
server and client expect it to be given when updating VIM.
