Title: MNT: Single function call to create an event

- The previous implementation formatted the event and then
published it to an epics PV. A server was monitoring that PV
and then wrote it into metadatastore. That's a stupid
implementation (sorry!) because then data can be lost if
the PV is overwritten before the server can grab it and
publish it to metadatastore

- This implementation just writes the event into metadatastore
and then publishes it to a PV. The only possible information
loss is in the live viewer which is not a big deal (Stuart
confirms that this is not a big deal)
