Probably 'all' should not be allowed for group names

I don't think that this is what I expected when I run this:

bessarabov@bessarabov-osx:~$ cat /Users/bessarabov/.spot_inventory.yaml
groups:
  all:
    - { host: "192.168.31.101", name: "h1" }
    - { host: "192.168.31.102", name: "h2" }

  other:
    - { host: "192.168.31.86", user: "pi", name: "h3" }
bessarabov@bessarabov-osx:~$ spot --inventory=/Users/bessarabov/.spot_inventory.yaml --target=all date
spot v0.9.1-0aa555f-2023-05-02T08:06:47Z

heh, you confused the system by setting "all" group, which is a reserved word. I'll add a check and will reject such group name

I'm closing this conversation, because there is an issue for this #43

Thank you!
