allow sorting to be configured globally (closes hetznercloud#418)
I am a heavy user of the hcloud-cli. However, I really don't like the default sorting by server-id, and would prefer sorting by age (see hetznercloud#417/hetznercloud#420) or name. Currently, I always type `hcloud server list -s name` to sort by name. since the `-s` flag is part of the `list` subcommand and not the `hcloud` base command (like in many other software that makes use of the Cobra framework), I cannot simply `alias hcloud-"hcloud -s name"` in my shell to default the sorting to "by name". This commit adds a `[defaults]` section to the config toml which allows to override the default sorting behavior for individual `hcloud` subcommands. The following behavior is used to determine the sorting-order | config file | flag | result | |-------------|---------|----------------------| | not-set | not-set | sort by id (default) | | not-set | set | sort by flag value | | set | not-set | sort by config value | | set | set | sort by flag value |
