This change introduces the --ipv6-only-mgmt flag for testbed-cli.sh to configure DUTs with IPv6-only management interfaces, eliminating IPv4 from the management network. Key changes: - testbed-cli.sh: Add --ipv6-only-mgmt flag for gen-mg, deploy-mg, test-mg - config_sonic_basedon_testbed.yml: Handle IPv6-only minigraph deployment with proper async handling for management IP transition - minigraph_dpg.j2, minigraph_dpg_asic.j2: Conditionally include IPv4/IPv6 management interfaces based on use_ipv6_mgmt flag - group_vars/*/ipv6.yml: IPv6 service configurations (NTP, DNS, syslog) - setup-ntp-server.sh: Docker-based Chrony NTP server for local time sync - pr_test_template.yml: Add CI jobs for IPv6-only management testing - Documentation updates for setup and troubleshooting The local NTP server (fec0::ffff:afa:2) ensures reliable time synchronization when external IPv6 NTP servers are unreachable.

Changes required to get sanity check and pretests to pass in an IPv6 only mgmt environment. - Add -6 to run_tests.sh to run tests in IPv6 only mgmt setup - Add --ipv6_only_mgmt option to conftest - Modify base.py init method to detect IPv6 only mgmt setup and initialize mgmt_ip accordingly - Modify checks.py and reboot.py to use IPv6 address for pings Signed-off-by: opcoder0 <110003254+opcoder0@users.noreply.github.com>

Is there a way to avoid using global variable?

It is better to use is_ipv6_address defined in tests.common.utilities to check if it is IPv6 address here.

Description of PR
This PR adds test framework support for running SONiC tests in IPv6-only management network environments. When enabled, the test framework uses IPv6 addresses for DUT management connectivity and skips IPv4-specific sanity checks.
This complements the existing --ipv6-only-mgmt support in testbed-cli.sh (#22310) by adding the necessary test infrastructure changes.

Fixes # (issue)

Approach
What is the motivation for this PR?
Pretest needs to work in an IPv6 only management environment. The PR contains changes to invoke tests in such an environment and pretest checks.
How did you do it?
Changes include
run_tests.sh: Add -6 flag for IPv6-only management mode; fix pretest/posttest by adding . path argument
conftest.py: Add --ipv6_only_mgmt pytest option and ipv6_only_mgmt_enabled session fixture
base.py: Use IPv6 address as mgmt_ip when IPv6-only mode enabled
checks.py: Skip IPv4 management ping check when mgmt_ip is IPv6
reboot.py: Use ping6 for IPv6 management addresses
To run tests in IPv6 only management setup pass -6 to run_tests.sh. Example Usage -
How did you verify/test it?
Locally.
Any platform specific information?
None
Supported testbed topology if it's a new test case?
None
Documentation
Updated in ipv6-management-setup.md and README.testbed.VsSetup.md.
