Allow float value for timeout

[coignetp]

What does this PR do?

We allow float values for timeout in code

integrations-core/statsd/datadog_checks/statsd/statsd.py

Line 23 in 4b7527e

timeout = float(instance.get('timeout', 10))

But we converted it to int anyway with the config models https://pydantic-docs.helpmanual.io/usage/types/
