Found by building a node from nothing. Its agent tried to install libgomp1
while cloud-init and unattended-upgrades were running apt, and failed with
"Unable to lock directory /var/lib/apt/lists/": DPkg::Lock::Timeout covers
dpkg's lock, not the one `apt-get update` takes on its lists. The node was
correctly kept out of placement and said why, and then sat idle for the ten
minutes until the next pass.
A package command that fails only on a held lock is now retried for up to
ten minutes, reported as "waiting for another apt-get to finish" rather than
as a failure. A pass that does fail is retried after a minute, backing off to
ten.
The weights directory is created when the agent starts rather than by the
first download, so a new node reports its disk from its first heartbeat.
Onboarding takes several control plane addresses, comma separated, so a new
node gets the same failover list as the rest.
