Adds new verification to expectation_parser.py

Currently typ accepts tags that are a part of multiple tag sets.
This change will add a new verification that will make sure each
tag set is mutually exclusive. If this rule is violated, then a
ParseError exception will be thrown and will contain an appropriate
message. I also added a new unittest,
testParseExpectationMutuallyExclusiveTestSets in
expectations_parser_test.py for this change

Catapult

These tools were created by Chromium developers for performance analysis, testing, and monitoring of Chrome, but they can also be used for analyzing and monitoring websites, and eventually Android apps.
