Idea: add wildcard support for mgrctl cp

[stdevel]

Hi folks,
when using mgrctl cp only one file at the same time can be copied, e.g.:

uyuni-server:~ # mgrctl cp a server:/root/a
10:01AM INF Starting mgrctl cp a server:/root/a

It would be handy having the possibility to copy multiple files at the same time. Currently, this is not possible as the cp subcommand only accepts 2 arguments:

uyuni-server:~ # mgrctl cp a b server:/root/
Error: accepts 2 arg(s), received 3

Currently, a shell loop workaround is needed for this, e.g.:

# for i in a b; do mgrctl cp $i server:/root/ ; done
10:05AM INF Starting mgrctl cp a server:/root/
10:05AM INF Starting mgrctl cp b server:/root/

Hi @stdevel! I've been diving into the uyuni-tools codebase recently and I would love to take a stab at this if no one else is currently working on it.

The plan would be to update the Cobra command definition to accept MinimumNArgs(2), treat the last argument as the destination directory, and loop through the preceding arguments to perform the copy operations. Let me know if that sounds like the right approach

Ohai @YatesMold,
thanks for stepping in - this sounds very promising!

Thrilled to hear what the Uyuni developers think about your PR. 👍🏻
