need the keys for el7

[Sérgio Basto]

Hi kwizart, 
I updated rpmfusion-free-release and nonfree , for rawhide , f24 and
f23 , fixing f25 symlink. Please check it .

Shouldn't we also add el-5 , 6 and 7 keys to rpmfusion-{non}free-
release ? 

Anyway I'd like add  el7 keys to  distribution-gpg-keys package so
where is RPM-GPG-KEY-rpmfusion-free-el-7 and RPM-GPG-KEY-rpmfusion-
nonfree-el-7? 


Thanks,
Com os melhores cumprimentos,
