Remove agent_update from the compute manager.

It appears that this method of the compute method has never been used
since it was added in fa0b64b500f3a196044459ba4bf8ed0dea214e92, so just
remove it.

It was also added to the virt driver API, but the only use is internally
to the xenapi driver, so leave it as an internal thing to that driver
only.

Part of blueprint no-db-messaging.
