Add brace expansion in talosctl

Description

It would be pretty handy to allow run commands like that:

talosctl apply-config --nodes 10.0.0.{5..15}

kubectl supports this btw

[nberlee]

To my understanding, brace expansion is a shell feature, similar to how wildcards work. This is why it functions seamlessly with commands like kubectl uncordon, which inherently support processing multiple nodes at once.

In contrast, talosctl --nodes requires nodes to be explicitly separated by commas rather than spaces, which is your problem I think. as --nodes is a parameter which can only have one value

[rothgar]

@nberlee is correct. This is a shell feature and the fact that nodes requires a comma between nodes. You can replace the space with a comma with something like this

talosctl apply -n $(echo 10.10.1.{1..10} | tr ' ' ,)
