arista: monkey-patch CliPlugin.ReloadCli for cEOS gNOI System.Reboot

Upstream cEOSLab disables the EOS `reload` and `show reload` CLI commands
via `CliPlugin.ReloadCli.notCeosGuard`, causing Octa's `gnoi.system.Reboot`
handler (which executes `show reload` followed by `reload in 0 force` via
ConfigAgent) to fail with `Cli command execution failed`.

Mount a `usercustomize.py` hook into `/mnt/flash/usercustomize.py` via the
`<node>-config` ConfigMap and set `PYTHONPATH=/mnt/flash` in the container
environment so that EOS CLI processes (`ConfigAgent` and `Cli`) intercept
`CliPlugin.ReloadCli` on import. When `notCeosGuard` is active, the hook
lifts the guard and replaces `doReload` with a handler that halts `systemd`
(PID 1) via `SIGRTMIN+3`, allowing `kubelet` to restart the container in
place while preserving the pod network namespace and startup config. Once a
future EOS release natively supports `reload` on cEOSLab, `notCeosGuard`
returns `None` and the hook becomes a no-op.
