An
com.tc.config.schema.IllegalConfigurationChangeHandler that prints
a message to the screen and the logs, and then exits.
NOTE: this code should no longer be engaged since the configuration modes
were slimmed down to production and development. In production the client
config is checked to match that of the servers. In development, the
client's config simply applies to that client, whereas it used to be
broadcast to other clients. Basically, config values cannot change after
startup anymore.
