running out of space on jenkins master

[Eyal Edri]

hi,

since we have limited space on jenkins.ovirt.org (50GB),
we need to keep less hisotry of artifacts and builds

most of the projects keep today a history of 10-50 builds back.

it also keeps only 20 builds back with artifacts.

not sure when is the due date on moving the jenkins server out of EC2, 
but if we're going to stay there for a while, we'll need to free some files.

for e.g., ovirt-node iso files takes quite a lot:

[root at jenkins var]# find . -printf '%s %p\n'|sort -nr|head

how much do we really need to keep? 
if we've copying nightlies to ovirt.org, it might be redundant..
