nodejs-packaging repo

[Tom Hughes]

As fedorahosted is going away I have created a pagure repo to replace 
the nodejs-packaging repo on fedorahosted:

https://pagure.io/nodejs-packaging

I have also created a nodejs-sig group on pagure that has push access to 
that repo and added various SIG members to it.

Issues and PRs from the repo should be notified to the sig list.
