Due to the constraint, pretty old version is being used. Update
the cpuid package to the latest master to get, e.g., AVX512_VNNI
and VMX detection.

Refactor NFD into a simple server-client system. Labeling is now done by
a separate 'nfd-master' server. It is a simple service with small
codebase, designed for easy isolation. The feature discovery part is
implemented in a 'nfd-worker' client which sends labeling requests to
nfd-server, thus, requiring no access/permissions to the Kubernetes API
itself.
Client-server communication is implemented by using gRPC. The protocol
currently consists of only one request, i.e. the labeling request.
The spec templates are converted to the new scheme. The nfd-master
server can be deployed using the nfd-master.yaml.template which now also
contains the necessary RBAC configuration. NFD workers can be deployed
by using the nfd-worker-daemonset.yaml.template or
nfd-worker-job.yaml.template (most easily used with the label-nodes.sh
script).
Only nfd-worker currently support config file or options. The (default)
NFD config file is renamed to nfd-worker.conf.
Glide is not actively developed anymore, and, its documentation
recommends migrating to dep. Also, dep is widely used in other k8s
projects.
Migrating to dep dramatically reduces the size of the populated vendor/
directory from 75MB down to about 20MB.
