Description

Currently we can output using Go templates: scw instance server get <id> -otemplate="{{ .ID }}".
This can be complicated to use with advanced features like arrays, scw instance server get <id> -otemplate="{{ index 0 .PublicIPs }}".

We should investigate the usage of jsonpath like in kubectl to have an easier interface for output configuration.

How I imagine scw could expose this functionality

scw instance server get <id> -ojsonpath="{ .PublicIPs[0] }"
