dougbtv 528d4f150c Functionality for Aux CNI Chain using subdirectory based CNI configuration loading.
Removes the it `fails to execute confListDel given no 'plugins' key"` test.

This test no longer fails after libcni version 1.2.3.
It probably shouldn't failduring a DEL action as it is, we want the least error prone path.

The GC test now uses both cni.dev attachment formats.

Uses both attachment formats as per https://github.com/containernetworking/cni/issues/1101 for GC's cni.dev/valid-attachments & cni.dev/attachments
