getistio list: Add name column

[ZhiHanZ]

current we support to fetch istio through name

getistio fetch --name 1.9.0-tetrate-v0

above command could fetch istio version 1.9.0 in flavor tetrate with flavor version 0
and we also support to switch to given istio version through name

getistio switch--name 1.9.0-tetrate-v0

the name of each distribution did not shown and user need to figure out name by themself which is not user friendly, thus we want to show the column data in format like:

NAME	ISTIO VERSION	FLAVOR	FLAVOR VERSION	K8S VERSIONS
1.9.0-tetrate-v0	*1.9.0	tetrate	0	1.17,1.18,1.19
1.9.0-tetratefips-v0	1.9.0	tetratefips	0	1.17,1.18,1.19
1.9.0-istio-v0	1.9.0	istio	0	1.17,1.18,1.19

I would prefer that NAME be on the leftmost
@deva26 WDYT?

@ZhiHanZ Could you please put the context about why we start thinking of having NAME column in the issue description?
