LogStoreDefinition exposes a bogus write-attribute handler for its 'type' attribute

The 'type' attribute of LogStoreResource isn't really read-write. Its value is determined by attributes of the parent resource. The OSH for write-attribute is ReloadRequiredWriteAttributeHandler, and when the reload happens whatever value is set will be lost.

For 8.0.1 I'll have the OSH just log a WARN. The attribute should be made read-only for 9. I could make it read-only for 8.0.1 but I don't want to do a management API bump, introduce transformation etc.
