[Enhancement] Should async_std be replaced with tokio ?

[Hennzau]

Current behaviour and limitations

Since #261, Zenoh-Flow has been based on Zenoh 1.x. A major change in this version of Zenoh is that task management has shifted from async_std to tokio (eclipse-zenoh/zenoh#1264).

Should Zenoh-Flow migrate entirely to tokio?

Proposed solution?

Hi @Hennzau!

In short, yes we should probably switch to Tokio.

The longer answer is that we had internal plans to use a patched version of async-std to provide additional functionalities. For instance, assigning a priority to a task. Unfortunately, due to external factors, these plans are now postponed and to have a more consistent software stack between the Zenoh and Zenoh-Flow projects, Tokio is the better default.

Alright! Yes, I remember M. Angelo C mentioning this version of async_std.

I’ll update the code to use tokio!
