REFL: IOC Log should be written to the database

[John-Holt-Tessella]

As a user I want my log entries from the refl ioc to be written to the message table in the database so that I can interogate them using the IOC Log view.

Acceptance Criteria

• Logged messages are sent to the epics logger

Notes

The logger which displays messages in ibex should also send those messages to the epics log channel. There is probably code to support this already since it does the put log messages.
Not asked for by a user but to make it consistent with non-python IOCs.
