mirrormanager: use the new mirrorlist cache generation tool

The new mirrorlist cache generation requires now less than one minute.
This includes pushing the data to the proxies. It also runs now every 15
minutes instead of once an hour.

The sync_pkl_to_mirrorlists.sh script has been renamed to
sync_cache_to_mirrorlists.sh as it no longer copies a Python pickle and
it also copies the data to only proxies at the same time instead of one
proxy at a time.
