Make TerminalIPythonApp message configurable while loading bsui #115
Description
Requested by @andrewmkiss in NSLS2/srx-profile-collection#18 (comment):
While loading bsui, we see a message [TerminalIPythonApp] Running file in user namespace...[filepath + name]. And then I have my own (much shorter), Loading file {filename}.... Can we remove this TerminalIPython message?
