Bring timeout support for scheduled tasks in aioclock

[mahdihaghverdi]

What's new

Groups

Set a timeout for a group of tasks.

group = Group(timeout=4)

@group.task(trigger=Every(...))
async def _(...):   # this task will fail every time it runs
    await asyncio.sleep(6)  

set a timeout for each task

group = Group(timeout=4)

@group.task(trigger=Every(...))  # this task has the group's timeout
async def _(...): ...

@group.task(trigger=Every(...), timeout=3)  # this task has its specific timeout
async def _(...): ...

App

set a timeout for each task

app = AioClock()

@app.task(trigger=Every(...))  # this task does not have a timeout
async def _(...): ...

@app.task(trigger=Every(...), timeout=3)  # this task has its specific timeout
async def _(...): ...

PS

I didn't know how to write tests for this feature, however all old tests are passed.
