A client should declare the "bridge" network fingerprint only if the bridge CNI plugin is available. Currently, Linux clients with the bridge kernel module enabled (pretty much all Linux boxes with Docker installed) declare "bridge" network, but allocs requiring it will fail with `failed to find plugin "bridge" in path [/opt/cni/bin]` error.

cni_path can contain multiple : delimited paths, so this needs to use filepath.SplitList and loop over the paths.

Closing this one as it was implemented in #15452. |
