  - Merge "[PDF] check-jinja: Filter-out incompatible PDF/IA"
  - [PDF] check-jinja: Filter-out incompatible PDF/IA

    While checking all PDFs against all installers, some mandatory
    requirements are sometimes not met:
    - minimum cluster nodes (e.g. Apex requires 5 nodes, 1 PDF has 3);
    - minimum interface count (e.g. Compass requires min 3 NICs, some
      PDFs only have two interfaces or less);

    The added filter is far from ideal:
    - node requirements are based on the latest (not highest) index
      used by the installer adapter to accomodate special handling of
      3-node cluster in Daisy templates;
    - interface req is based on the average interfaces/node, with
      quite some margin - this is a very loose mechanism;

    With this in, `check-jinja` has a return code of 0 (note that
    yamllint failures of output files are not affecting the return code).
