Revert "Use canonical hostname instead of ip by default (#16386)"

[adarshsanjeev]

This reverts commit 9459722.

Reverts the change to use canonical hostname instead of ip by default.

This change caused an issue with docker images, and requires the parameter DRUID_SET_HOST_IP=1 to be set to maintain previous behavior, which is backward incompatible.
