css.sdb.InteractionHandler is deprecated, as it does not only handle database related interactions,

In today's architecture, there's only one central css.task.InteractionHandler, which is to be used
for all requests. Depending on configuration information, it decides which handler implementation
to delegate a request to.
SQLExceptionInteractionHandler is the delegatee which handles only database related interactions.
LegacyInteractionHandler is the version which first checks for a database related interaction, and
forwards everything else to the css.task.InteractionHandler.
