Show source of exception in facility log message summary, such as:

(from user input)

2022-07-13 15:44:44	
  In [2]: abc()
  Exception: ValueError: this is the exception message
  File: /cds/home/k/klauer/Repos/hutch-python/raiser.py line 9

(from a thread - showing the closest input number)

  Thread: Thread-51
  Last user input [2]: abc()
  Exception: RuntimeError: this is the exception message
  File: /cds/home/k/klauer/Repos/hutch-python/raiser.py line 5

Motivation and Context

The current message is insufficient to get an idea of what happened (from Grafana):

2022-07-13 12:40:28	
  Line: 31
  Input: tmo_laser.lens_z.limits()
  Exception: TypeError: 'NoneType' object is not callable

pcdsutils will need an update to include this information in the JSON sent to logstash as well.
