* Handle incompatible_mapping_exception caused by another instance
* Cleanup logging
* Fix/stabilize integration tests
* Add REINDEX_SOURCE_TO_TARGET_VERIFY step
* Strip tests archives of */.DS_Store and __MAC_OSX
* Task manager migrations: remove invalid kibana property when converting legacy indices
* Add disabled mappings for removed field in map saved object type
* verifyReindex action: use count API
* REINDEX_BLOCK_* to prevent lost deletes (needs tests)
* Split out 100k docs integration test so that it has it's own kibana process
