Executor::spin_some, spin_all, spin_once are odd function names

Executor::spin_some, Executor::spin_all and Executor::spin_once are odd function names, as they do not give a good idea of what the functions intention is. Multiple developers in my company ran into this issue, and used the wrong functions for their use case, especially spin_some and spin_all are confusing.
Therefore I would vote to deprecate these and replace them by

something like :

void execute_all_ready_events();
void execute_one_ready_event();
void execute_all_ready_events_for();
void execute_all_ready_events_until();

void execute_for();
void execute_until();

Start by reviewing the Executor::spin_some, Executor::spin_all, and Executor::spin_once declarations and their call sites. The issue does not name files, tests, or a settled replacement API, so first establish the accepted naming and deprecation scope. Done means the API direction is agreed and the affected interfaces and uses are consistently migrated.
