* As a part of bringing functional testing to plugins, esArchiver gives these plugins a way to capture and reload es indexes without needing to write a bunch of custom code. It works similarly to the elasticDump and ScenarioManager tools that it replaces.
Differences:
- Streaming implementation allows for much larger archives
- CLI for creating and using archives
- Configurable archive location
- Stores the data in gzipped files (better for source control, searching, large archives)
- Automatically identifies and upgrades Kibana config documents
Methods:
- `#load(name)`: import an archive
- `#loadIfNeeded(name)`: import an archive, but skip the documents what belong to any existing index
- `#unload(name)`: delete the indexes stored in an archive
CLI operations:
- `./bin/es_archiver save <name> [index patterns...]`: save the mapping and documents in one or more indexes that match the wild-card patterns into an the `<name>` archive
- `./bin/es_archiver load <name>`: load the mapping and documents from the `<name>` archive
* [functional_tests/common/nagivate] check for statusPage
* [es_archiver] move bins into new scripts dir
* [functional_tests/apps/context] use esArchiver
* [esArchiver] general improvements after showing to a few folks
- remove auto-upgrading config doc logic (until we have better access to kibana version info)
- export unload command
- remove preemptive checks in favor of reacting to errors
- use type "doc" vs "hit" for doc records (consistency)
- wrote a bunch of pending tests to think though and plan
* [esArchiver] make log a stream that writes to itself
* [esArchiver] fill in stats and archive format tests
* [esArchiver] splitup action logic
* [esArchiver/cli] fix cli --help output and comment
* [esArchiver] remove type-based param coercion
* [esArchiver/log] use strings for log levels
* [esArchvier] remove unused var
* [esArchiver/indexDocRecordsStream] add tests
* [esArchive] fill in remaining tests
* [esArchiver] fix dem tests
* [eslint] remove unused vars
* [esArchiver/loadIfNeeded] fix call to load()
* [esArchiver] remove loadDumpData helpers
