Background

This default option actually breaks deploys because it provides the name of an existing logging bucket that is invalid.

Notably, this is already documented here: https://www.streamalert.io/en/release-3-0-0/config-global.html#s3-access-logging

[ryandeivert]

can you just remove the full block s3_access_logging block? it has sane defaults and is not needed here. docs outline the settings well if users want to use it
