Ability to customize how objects are repr()'d

[brianr]

pyrollbar uses reprlib to get representations of objects gathered as local variables. This means that to customize it, the only current option is to define/override __repr__. That isn't a good option in some cases, including:

• objects coming from external libraries
• objects where something else depends on the existing __repr__ implementation

Creating this issue to discuss the design for how to make this customizable.

Thanks for starting the convo, Brian.

I would probably expose a new configuration option that would allow the user to provide a function that would be used instead of __repr__() when serializing the local variable data.

e.g.

# Ordered list of serializers. The first regex pattern that 
# matches the object being serialized will be used. 
# If none of the user-supplied patterns match, the default 
# reprlib.repr() serializer will be used.
serializers = [
  ('class_name_regex_pattern', my_custom_serializer_fn)
  ('*', reprlib.repr)
]

+1 as is. It might be nice to support a __rollbar_repr__() convention of some kind for internal code.

We need to make sure the solution to this addresses the problem that this pull request attempted to address. #91

Would be nice to have this option!

Another option here could be to use devtools for formatting.
