Python Timer Triggers on the Linux Consumption Plan do not Timeout.

#### Investigative information

Please provide the following:

- Timestamp:
- Function App version (1.0 or 2.0):2.0
- Function App name:testfinpyfunction
- Function name(s) (as appropriate): TimerTrigger
- Invocation ID: c4128915-9119-4310-8b6b-c8c0210cfc1b
- Region:West Europe

#### Repro steps

Provide the steps required to reproduce the problem:

1. Create a new Python Function App.
2. Add a Timer Trigger (see code below)
3. Add a HTTP Trigger (see code below)
4. Update the Host.json so that the Timeout is 1 minute.

{
"version": "2.0",
"functionTimeout":"00:01:00"
}

#### Expected behavior

Provide a description of the expected behavior.

1. That the Function App should stop the Timer Trigger after 1 minute.

#### Actual behavior

Provide a description of the actual behavior observed.

1. The Timer Trigger doesn't timeout and the restart of the Functions Host will retry this invocation.

```Timer
import datetime
import logging
import time

import azure.functions as func

async def main(mytimer: func.TimerRequest) -> None:
utc_timestamp = datetime.datetime.utcnow().replace(
tzinfo=datetime.timezone.utc).isoformat()
time.sleep(660)
if mytimer.past_due:
logging.info('The timer is past due!')

logging.info('Python timer trigger function ran at %s', utc_timestamp)
```

```Http
import logging

import azure.functions as func
import time

async def main(req: func.HttpRequest) -> func.HttpResponse:
logging.info('Python HTTP trigger function processed a request.')
time.sleep(660)
name = req.params.get('name')
if not name:
try:
req_body = req.get_json()
except ValueError:
pass
else:
name = req_body.get('name')

if name:
return func.HttpResponse(f"Hello {name}!")
else:
return func.HttpResponse(
"Please pass a name on the query string or in the request body",
status_code=400
)
```

Start with the host.json setting for functionTimeout and the TimerTrigger invocation described in the issue. Reproduce the Python Timer Trigger with the supplied 660-second delay, then compare its behavior with the HTTP Trigger; done means the Timer Trigger stops after the configured one-minute timeout and does not retry the same invocation after host restart.
