This PS replaces deprecared module pkg_resources,
also fixes some unit tests and fixes the schema
validation by adding specific schema draft to
choose in order to prevent the processor to fall
back to use the latest draft that may potentially
cause issues.
Also this PS bumps kubectl version to 1.32.0 due
to CVE and switched base ubuntu image repo to
quay.io/airshipit
