The get_distribution load was very heavy, so follow the other parts and
just hardcode the version in. Also update bump-version to work with this
and with the new pyproject.toml configuration, and add a custom
user-agent to the API requests leveraging this version.
A missing snapshot could cause an exception here which would break the
entire autobackup run. Catch the exception and continue on as this
should never be a fatal situation.
used_bytes is a broken value since it does not take object replicas into
account, thus throwing off these calculations. Use stored_bytes instead
which properly represents this value.
Moves the age human conversion logic to the client so that this value
can be used by API consumers programatically.
Rounding ensures recent snapshots are not showing as "older" than they
actually are, which is important for accuracy especially with
automirror snapshots and ages above half the next rounding value.
Allows shipping snapshots automatically to remote clusters on a cron,
identically to how autobackup handles local snapshot exports.
VMs are selected based on configured tags, and individual destination
clusters can be specified based on a colon-separated suffix to the
tag(s).
Automirror snapshots use the prefix "am" (analogous to "ab" for
autobackups) to differentiate them from normal "mr" mirrors.
1. Ensure the local connection is actually always present if it exists,
and stored in the store file.
2. Remove any invalid "local" store entries if present (i.e.
pvcapid.yaml entries from legacy versions).
3. Order the connection lists such that "local" is always first.
4. Improve pretty list output format such that all fields are wider if
needed
