fix: revert value for ClickHouse HTTP settings

ClickHouse version 23.6 featured a backwards-incompatible change that
broke some of our existing tooling. This PR uses the old default value
and provides a way to override other settings that need to be configured
at the user level (previously we only needed to override global
settings).
