* Pipeline store can now only start when there is no .ingest index or all primary shards of .ingest have been started
* IngestPlugin adds`node.ingest` setting to `true`. This is used to figure out to what nodes to send the refresh request too. This setting isn't yet configurable. This will be done in a follow up issue.
* Removed the background pipeline updater and added added logic to deal with specific scenarious to reload all pipelines.
* Ingest services are no longer be managed by Guice. Only the bootstrapper gets managed by guice and that contructs
all the services/components ingest will need.
