IMPALA-8567 : Improve failure messages for insert events

This patch adds the exception to the error message during processing of
Insert events to improve debugging ability in case of errors.

Also, refactors the existing tests for insert events into util methods
which can be reused for other tests. Added a new test case which
generates a insert event on a table which has been dropped. This
scenario was seen while debugging test failures reported in IMPALA-8567.
Although, in this case the test does not error out.

Testing done:
Ran existing tests for events processor
