Feature/pybind11 experimental lift entry watchdog

[tongkiat]

Added some python bindings

Added python binding for C++ function rmf_fleet_adapter::agv::RobotUpdateHandle::Unstable::set_lift_entry_watchdog.

Added python binding for C++ enum rmf_fleet_adapter::agv::RobotUpdateHandle::Unstable::Decision.

I know these are unstable APIs. I'll amend them if/when the C++ function and/or enum changes.

Also, I'm wondering whether it's OK if I contribute the python version of the full_control fleet_adapter. In addition, I'm thinking of writing an accompanying article or note to help more people implement their own fleet_adapters. I hope this will pique the interest of more causal tinkerers (like me) and, perhaps, encourage/nudge these people to experiment or adopt RMF for their own just-for-fun projects. 😄

Thanks for your PR. Overall this looks good, just dropped in one small comment.
For sure we absolutely welcome any external contributions and encourage people to try out RMF! On a side note, you can also refer to our mir fleet adapter: https://github.com/osrf/fleet_adapter_mir/. Also we will soon (in this few weeks) release another py-based fleet adapter example template for easy integration, hopefully this can be a good reference for you. Will drop in the link once it's ready.

Maybe we can explicitly mention this as unstable, or create an unstable def_submodule.
