Describe NFD deployment via the operator. Add minimal documentation for uninnstalling NFD. Add instructions and template spec for running "nfd-master --prune". Also modify the RBAC rules in nfd-master spec template to make it possible doing --prune (allow nfd-master to list nodes in the cluster).

## Enable TLS authentication
|
|
## The example below assumes having the root certificate named ca.crt stored in
|
|
## a ConfigMap named nfd-ca-cert, and, the TLS authentication credentials stored
|
|
## in a TLS Secret named nfd-master-cert.
|
|
## Additional hardening can be enabled by specifying --verify-node-name in
|
|
## args, in which case every nfd-worker requires a individual node-specific
|
|
## TLS certificate.
|
|
# args:
|
|
# - "--ca-file=/etc/kubernetes/node-feature-discovery/trust/ca.crt"
|
