Tune httpx keep alives for polling integrations (#95782)

Browse Source 
* Tune keep alives for polling integrations

aiohttp closes the connection after 15s by default,
and httpx closes the connection after 5s by default.

We have a lot of integrations that poll every 10-60s
which create and tear down connections over and over.

Set the keep alive time to 65s to maximize connection
reuse and avoid tls negotiation overhead

* Apply suggestions from code review

* adjust
