vtysh, lib: preprocess CLI graphs
Store a parsed and built graph of the CLI nodes in vtysh, rather than
parsing and building that graph every time vtysh starts up.
This provides a 3x to 5x reduction in vtysh startup overhead:
`vtysh -c 'configure' -c 'interface lo' -c 'do show version'`
- before: 92.9M cycles, 1114 samples
- after: 16.5M cycles, 330 samples
This improvement is particularly visible for users scripting `vtysh -c`
calls, which notably includes topotests.
