The constaint was supposed to be 50% of one CPU core, or 500 millicores
as per Kubernetes nomenclature.

This patch adds support for flexible columns. When a column is marked
as flexible it means it can be stretched when printing the table to an
optional minimal table width. Multiple columns can be marked and when
this occurs the padding is applied equally to all columns.
Also, make sure to only add 2 char padding between columns, not always
at the end, or we will require larger terminal than necessary.

- Remove fixed lengths from Column class
- Add dynamic width calculation to SimpleTable
- Update service table to use new batched printing

Verify that if the system encounters a hard lockup, i.e., interrupts
are no longer being serviced, then the system's watchdog will
correctly reboot it.
By default, ensure that the target device accepts TCP connections on
the specified port before returning the device object. This aligns the
SSH implementation with {NET,REST}CONF.
This solves the issue where tests that use SSH commands early in their
execution would sometimes fail as the remote server had not started up
yet.
Store historical snapshots as compressed .json.gz files to reduce disk
usage. The operational.json file remains uncompressed for easy access.

Dump operational datastore to timestamped JSON snapshots every 5 minutes
(in /var/lib/statd/). The operational.json symlink always points to the
latest snapshot.
Implement hierarchical retention policy that keeps the first snapshot of
each time period (hour/day/week/month/year), providing fine-grained recent
history while preventing unbounded disk usage.
This will allow us to plot / track how the system state evolves as
well as give us somewhat fine-grained info in the case of an event,
such as a crash.
Add unit test simulating months of snapshots to verify retention
behavior using a statd stub that only runs the retention code locally
(unit test)

This patch adds diagnostic data and additional logging to catch the root
cause for issue #1303:
- Exactly when and why cleanup is called
- Whether the cd /tmp command succeeds
- The actual tar exit code (not just 255 from SSH)
- Whether cleanup happens before tar completes (race condition)
- The full collection.log showing the sequence of events

This (new) test sometimes fail on HW, so let's hold off a while before
sending our log messages. Ths should allow the DUTs to settle.

Let's drop the leading IETF or Infix prefixes from tests. Initially the
idea was to mimnic the YANG models, but it's difficult to navigate and
does not provide any real benefit to developers or end-users.

Set PYTHONPYCACHEDIR=/tmp/__pycache__ in test/env to avoid permission issues
during git cleanup operations. When tests run in Docker containers as root,
__pycache__ directories and .pyc files end up owned by root, preventing the
CI user from cleaning them up.

This change exposes the macvlan mode to tests, unlocking support for running
certain types of tests on systems with only a single Ethernet port.

- Basic DHCPv6 client, request a lease and verify Linux installs a
default route from the Router Advertisements (option not included
in DHCPv6), hence the 'enable-ra' option to dnsmasq. Also verify
DNS resolution over IPv6, including the resolvconf dance
- Prefix delegation, verifies that the client can actually request
and receives a prefix from a DHCPv6 server. We don't do anything
with it today though
Two new DHCP server implementations, the basic test relies on dnsmasq
and the prefix delegation test requires an ISC based dhcp server with
server side support for ipv6 prefix delegation. We could reuse the
latter for both tests, but this way we get compatibility testing.
