bolt command line: add to nodes when --nodes is passed multiple times

[jjtoth]

If I run this:

bolt command run --nodes=web5 --nodes=web6 'rpm -q puppet'

it only runs on the last host (or hosts given): "web6" in this case.

Motiviation is that i would use it in combination with this shell pattern:

bolt command run --nodes=web{5,6,7,8}.mydomain.edu 'echo hi, this is bolt'

or, even more likely:

bolt command run --nodes={web{5,6,7,8},elasticsearch{1,2,3}.subdomain}.mydomain.edu 'echo hi, this is bolt'

which would expand to:

bolt command run --nodes=web5.mydomain.edu --nodes=web6.mydomain.edu --nodes=web7.mydomain.edu --nodes=web8.mydomain.edu --nodes=elasticsearch1.subdomain.mydomain.edu --nodes=elasticsearch2.subdomain.mydomain.edu --nodes=elasticsearch3.subdomain.mydomain.edu 'echo hi, this is bolt'

Oops, didn't mean to close it.

@jjtoth PR #103 was just merged to resolve this issue.

Thanks @jjtoth. This should now be fixed (give bolt#master a try).
