nodeset resolution error with numeric group source

[thiell]

Reported during testing of 1.7.82

yaml file:

111:
    foo: 'bar'

$ nodeset -f @111:foo
nodeset: Unknown group source: "111"

$ nodeset -L | grep 111
@111:foo
$ nodeset -LL | grep 111
nodeset: Unknown group source: "111"

[thiell]

A workaround is to quote the dict key, like "111":. We will need a fix though as the behavior is not consistent in my example above, and this can be confusing for the users, so I guess we should either throw an error ~or convert 111 into a string~.

Why not convert it to a string? It's probably safe to assume that all group names and nodesets are strings anyway/
