[CentOS-devel] a snapshotted, delayed mirror

One of the corner case challenges that I have on the builders that do
the chained instance, images, media builds is that they consume an
internal mirror - but a generic mirror. i.e updates during the day can
result in the images that are built later to end up with different
content ( for the ones that consume the updates/ repo etc )

To work around this, I'm proposing running a mirror closer to the
image-buildsys machine, that only updates at midnight UTC, and will
represent the state of play on the calendar date before the timestamped
images. eg. the CentOS-7-x86_64-Generic-2014_08_26.qcow2 image will
contain updates upto and including all content released till the 25th

Its likely easier to make this private. But is there value in having
this be public ? its only going to be a single node ?

Also, longer term we might need / want to chain this from
ci.dev.centos.org runs, so we only include content thats been through
the ci process.
