Description

Rework of #3382, avoiding replacing '127.0.0.1' by 'localhost' if this was defined by the user using host

It also fixes options.host === false.

The hint to use host in the console is not shown if the user sets 127.0.0.1 by hand.

Fix #3355

After #2977, we lost the hostname defaulting to localhost for '127.0.0.1' and '0.0.0.0'

This PR adds that logic back, also including host === undefined and '::' that should be treated equally to '0.0.0.0'

The reported URL in the console also replaces '127.0.0.1' by localhost now.
