The caller is required to pass the "options" argument with the following
expected attributes:

dump_index_patterns - Don't do any indexing, but just emit the
list of index patterns that would be used
dump_templates - Dump the templates that would be used
index_tool_data - Index tool data only
re_index - Consider tar balls marked for re-indexing
All exceptions are caught and logged to syslog with the stacktrace of
the exception in a sub-object of the logged JSON document.
Signal Handlers used to establish different patterns for the three
behaviors:
1. Gracefully stop processing tar balls
- SIGQUIT
- The current tar ball is indexed until completion, but no other
tar balls are processed.
- Handler Behavior:
- Sets a flag that causes the code flow to break out of the
for loop.
- Does not raise an exception.
2. Interrupt the current tar ball being indexed, and proceed to the
next one, if any
- SIGINT
- Handler Behavior:
- try/except/finally placed immediately around the es_index()
call so that the signal handler will only be established for
the duration of the call.
- Raises an exception caught by above try/except/finally.
- The finally clause would take down the signal handler.
3. Stop processing tar balls immediately and exit gracefully
- SIGTERM
- Handler Behavior:
- Raises an exception caught be a new, outer-most, try/except
block that does not have a finally clause (as you don't want
any code execution in the finally block).
4. Re-evaluate the list of tar balls to index after indexing of the
current tar ball has finished
- SIGHUP
- Report the current state of indexing
- Current tar ball being processed
- Count of Remaining tarballs
- Count of Completed tarballs
- No. of Errors encountered
- Handler Behavior:
- No exception raised
