Group-Default plugin --pretend bug

[thebsdbox]

When using the --pretend flag to examine the possible outcome of a commit, a second --pretend will result in the group-default plugin becoming inconsistent and requiring a restart.

$ ./infrakit group commit oneview.json --pretend
Committing oneview would involve: Managing 4 instances
$ ./infrakit group commit oneview.json --pretend
Committing oneview would involve: Noop
$ ./infrakit group commit oneview.json
Committed oneview: Noop

The --pretend appears to change the internal state to "committed" resulting in actual changes not being performed afterwards.

Thanks for reporting! I'm able to repro from the tutorial as well:

$ build/infrakit group commit docs/cattle.json --pretend
Committing cattle would involve: Managing 5 instances
$ build/infrakit group commit docs/cattle.json --pretend
Committing cattle would involve: Noop
