fix: Use appropriate timeouts

[janbuchar]

• closes Refactor client timeouts - parity with Python implemenation #685
• modelled after refactor: Rework client timeout apify-client-python#384

+1 for extracting the consts somewhere, so we don't have those in multiple places

Sorry for the confusion around secs/millis - I changed my approach when working on this and stopped when the client_timeouts test started to pass 🤦

@B4nan @barjin I switched to milliseconds almost everywhere and I think the result is in fact much cleaner. If you want to skim it, go ahead. Otherwise I'll merge it later today.

Basically same issue like:
apify/apify-sdk-python#9

lgtm, thanks! 🚀
