This patch provides the necessary error handling while unpickling
a builder file. Earlier if a builder file is empty/invalid/corrupted,
the stacktrace was shown to user with an exit code of 1. This fixes it
to show a user-friendly message and also returns the exit code of 2,
indicating there was a failure.

Closes-Bug: #1370680
Add some tests for essential methods in swift-ring-builder.
Tests for removing or changing device settings are executed
with different search values to cover many possible command
line arguments.
Currently tested methods:
- create ring
- add device
- remove device
- set weight
- set info
- set min_part_hours
- set replicas
Tests use swift.common.ring.RingBuilder to verify actions.
Catching and testing output from print statements is not
tested, because this requires redirecting sys.stdout during
tests and that might have some sideeffects for testing tools.
bin/swift-ring-builder has been moved to swift/cli/ringbuilder.py
and slightly modified to work as before (mainly due to no more
existing global variables since that part of the code has been
moved inside a main() function).
