repo key gets added on every run

[ingardm]

In manifests/repo/debian.pp "key" points to $repo_name (which is datastax).
This variable is used in the puppet check to see if the key is already added. Its wrong to use $repo_name here, it should instead be "B999A372" (taken from apt-key list).

From puppet agent -t -d :
