feat(aosc): Add 'AOSC OS' support

Additional Context

AOSC OS is a general purpose Linux distribution under active maintenance by the Anthon Open Source Community since 2014. For further information, please visit the AOSC Portal.

Test Steps

Basic functionality tests have been successfully conducted on a Cloud environment powered by Openstack. Additionally, the cloud-init package has been merged into the main repository of AOSC OS.

However, we haven't released cloud images yet. You can download an iso, install the system manually, and runoma install cloud-init for testing purpose.

@leavelet , thanks for the contribution! Overall, I think things look good. Your newly added test fails. It looks like you need a mock to ensure hostnamectl doesn't get called on the system that unit tests are running on.
tests/unittests/test_cli.py::TestCLI::test_wb_schema_subcommand[all_spot_check] also fails, which checks the list of supported distros. Additionally, linting fails on cloudinit/distros/aosc.py:9:44: F401 [*] cloudinit.distros.rhel_util imported but unused.
