Swap reviews for Vagrant dependencies

[Josef Stribny]

Hi all,

please help me with the reviews of the following Vagrant dependencies:

rubygem-hashicorp-checkpoint
https://bugzilla.redhat.com/show_bug.cgi?id=1150152

rubygem-log4r
https://bugzilla.redhat.com/show_bug.cgi?id=1150151

I need them so I can make Vagrant an F22 feature.
I will happily do some reviews in exchange.

Thanks
Josef
