When nova_virtlogd container gets restarted the instance console auth
files will not be reopened again by virtlogd. As a result either
instances need to be restarted or live migrated to a different compute
node to get new console logs messages logged again.
Usually on receipt of SIGUSR1, virtlogd will re-exec() its binary,
while maintaining all current logs and clients. This allows for live
upgrades of the virtlogd service on non containerized environments
where updates just by doing an RPM update.
To reduce the likelihood in a containerized environment virtlogd
should only be restarted on manual request, or on compute node reboot.
It should not be restarted on a minor update without migration off
instances.
This introduces a nova_virtlogd_wrapper container and virtlogd wrapper
script, to only restart virtlogd on either manual or compute node
restart.
With NovaEnableVirtlogdContainerWrapper the virtlogd wrapper can be
disabled.
