Remove config initialization from init()

[padurean]

What happened helper.InitConfig gets called also for commands other than the currently running one.

What you expected to happen helper.InitConfig gets called only for the currently running command.

How to reproduce it (as minimally and precisely as possible) Add a println in the definition of helper.InitConfig and run any CLI - e.g. immuadmin. Observe that InitConfig gets called for other commands too - output example:

./immuadmin user list
~~~~~> config name immudb
Using config file: /Users/ogg/ws/github/immudb/configs/immudb.toml
~~~~~> config name immugw
~~~~~> config name immuadmin

Environment

./immuadmin version
Using config file: /Users/ogg/ws/github/immudb/configs/immudb.toml
immuadmin v0.6.1

Additional info (any other context about the problem) Initialisation code like this should be moved (for all CLIs) from init to NewCmd

func init() {
    cobra.OnInitialize(func() { o.InitConfig("immudb") })
}
