nfd-master: implement --instance flag
This can be used to help running multiple parallel NFD deployments in the same cluster. The flag changes the node annotation namespace to <instance>.nfd.node.kubernetes.io allowing different nfd-master intances to store metadata in separate annotations.

### --instance
|
||||
|
||||
The `--instance` flag makes it possible to run multiple NFD deployments in
|
||||
parallel. In practice, it separates the node annotations between deployments so
|
||||
that each of them can store metadata independently. The instance name must
|
||||
start and end with an alphanumeric character and may only contain alphanumeric
|
||||
characters, `-`, `_` or `.`.
|
||||
|
||||
Default: *empty*
|
||||
|
||||
Example:
|
||||
|
||||
```bash

nfd-master --instance=network

```
