Adds a check that a volume creation or resize won't violate the 80% full
rule for the storage cluster. This ensures a cluster won't get too full
if a storage volume fills up.
Also adds a force flag throughout the pipeline to override this check,
should an administrator really want to do so.
Closes#177
How this was being done didn't work, as the backup volume was already
unmounted when we tried to read the backups from it. Instead, populate
the backup summary earlier in the run, during the actual backup.
1. Use the actual response code from the server on error, or 504 on
timeouts instead of 500.
2. Retry GET requests 3 times and only error if the last fails
Shows each subarg of the task_args as its own element, if applicable,
and fits the width to the terminal using MAX_CONTENT_WIDTH instead of an
arbitrary value.
Adds a new flag to VM metadata to allow setting the VM live migration
max downtime. This will enable very busy VMs that hang live migration to
have this value changed.
Major improvements to autobackup and backups, including additional
information/fields in the backup JSON itself, improved error handling,
and the ability to email reports of autobackups using a local sendmail
utility.
Allows an administrator to easily generate a Prometheus file service
discovery configuration via the CLI for all clusters they have
configured. Assumes that all the various connection details are correct,
and due to the limits of the file SD config does not include the scheme
or SSL verification options (as these are global in Prometheus).
Ensures that messages are fully read before each append. Adds more
Zookeeper hits, but ensures logs won't be overwritten by multiple
daemons.
Also don't use a set on the client side, to avoid "removing duplicate"
entries erroneously.
