Roey BermanandGitHub 6263044d8c Implement operation cancelation executors (#5801)
## What changed?

- Implemented operation cancelation executors
- Fixed bug where we weren't correctly identifying service not found
errors
- Fixed bug where task would fail instead of operation when service is
not found
- Fixed bug where context timeout was on the task instead of the request
for callback and operation invocations preventing saving the result
- Moved `GenerateEventLoadToken` from being a mutable state method to a
static method as it does not require access to mutable state and makes
this method accessible in more contexts
- Added `LoadHistoryEvent` to the `MutableState` interface so it is
generated in the mock.

## Why?

Part of the functionality for nexus operations.
Note that in the future we'll want to support canceling a not yet
started operation. There are TODOs in the code base to address this. For
now if an operation is canceled before start is recorded, cancelation
isn't transmitted to the handler even though the operation may be
already started.

## How did you test it?

Added and rewrote tests.
