    Check for conflicting LogStore configs in the spark configuration.

    Check for conflicting LogStore configs in the spark configuration.

    To maintain compatibility across the Delta ecosystem, we accept keys both with and without the "spark." prefix. This means for setting the class conf, we accept both "spark.delta.logStore.class" and "delta.logStore.class" and for scheme confs we accept both "spark.delta.logStore.${scheme}.impl" and "delta.logStore.${scheme}.impl"

    If a conf is set both with and without the spark prefix, it must be set to the same value, otherwise we throw an error.
