What is included in the "connect" timeout?

[intgr]

Thanks for a more granular timeout system than requests!

I wish the documentation clarified a few details about the connect timeout: https://www.python-httpx.org/advanced/timeouts/#fine-tuning-the-configuration

The connect timeout specifies the maximum amount of time to wait until a socket connection to the requested host is established. If HTTPX is unable to connect within this time frame, a ConnectTimeout exception is raised.

• Does it include DNS resolution? Sounds like no. Maybe resolution should be a separate timeout parameter?
• Does it include the TLS handhsake? Seems to suggest no, but best if it was clarified.

I can submit a documentation PR once these are clarified.
