Filter out testfile metrics correctly when using collect[] filters (#763)
* remove injection hook for textfile metrics, convert them to prometheus format * add support for summaries * add support for histograms * add logic for handling inconsistent labels within a metric family for counter, gauge, untyped * change logic for parsing the metrics textfile * fix logic to adding missing labels * Export time and error metrics for textfiles * Add tests for new textfile collector, fix found bugs * refactor Update() to split into smaller functions * remove parseTextFiles(), fix import issue * add mtime metric directly to channel, fix handling of mtime during testing * rename variables related to labels * refactor: add default case, remove if guard for metrics, remove extra loop and slice * refactor: remove extra loop iterating over metric families * test: add test case for different metric type, fix found bug * test: add test for metrics with inconsistent labels * test: add test for histogram * test: add test for histogram with extra dimension * test: add test for summary * test: add test for summary with extra dimension * remove unnecessary creation of protobuf * nit: remove extra blank line
