Summary: Lingers on from D7271; Rename `ArcanistWorkingCopyIdentity.getConfig()`. Changed all linters (Except one) to use `getConfigFromAnySource()`, because it seems to make sense. Test Plan: arc unit --everything; arc lint in github.com:epriestley/arclint-examples.git (Except for phpcs, flake8, cpplint and csslint which I don't have installed).
