* Removes logging all the reader actions, and logs specific messages inside the reader_fsm instead
* Adds constructors to reader actions
* Makes reader_fsm use connection_state
* Refactors reader_fsm tests
* Moves exec_fsm action printing to test code
* Adds support for terminal and partial cancellation to async_run.
* Makes basic_connection::cancel use per-operation cancellation under the hood.
* Fixes a number of race conditions during cancellation which could cause the cancellation to be ignored. This could happen if the cancellation is delivered while an async handler is pending execution.
* Deprecates operation::{resolve, connect, ssl_handshake, reconnection, health_check}, in favor of operation::run. Calling basic_connection::cancel with these values (excepting reconnection) is now equivalent to using operation::run.
* Fixes a problem in the health checker that caused ping timeouts to be reported as cancellations.
* Sanitizes how the parallel group computes its final error code.
* Simplifies the reader, writer and health checker to not care about connection cancellation. This is now the responsibility of the parallel group.
* Removes an unnecessary setup_cancellation action in the reader FSM.
* Adds documentation regarding per-operation cancellation to async_receive.
* Adds additional health checker tests.
* Adds async_run per-operation cancellation tests.
* Adds reader FSM cancellation tests.
* Makes test_conn_exec_retry tests more resilient.
* Removes leftovers in the UNIX and TLS reconnection tests. These were required due to race conditions that have already been fixed.

Data rotation in the read buffer creates latency, we know it
is preset but so far its magnitude was unknown. This PR adds
it as a new field to the usage struct. For example, the
test_conn_echo_stress outputs now
