The udev Discovery Handler parses the udev rules listed in a Configuration, searches for them using udev, and returns a list of discovered device nodes (ie: /dev/video0). It parses the udev rules via a grammar [grammar](https://github.com/project-akri/akri/blob/main/discovery-handlers/udev/src/udev_rule_grammar.pest) Akri has created. It expects the udev rules to be formatted according to the [Linux Man pages](https://linux.die.net/man/7/udev).
Additionally, the permissions for the device mount are defined as well and are set to `rwm` (read, write, modify) by default.
