Review request for atlas.
Bugs: ATLAS-2085
https://issues.apache.org/jira/browse/ATLAS-2085
Repository: atlas
Description
-------
In HA deployments Atlas instances load bootstrap types during initialization
i.e. before leader election. When Atlas is brought up for the first time, this
will initialize the store with the types defined in the model files.
Index setup kicks in when an instance is activated -
GraphBackedSearchIndexer.initialize(); this looks for a specific property name
('__type') in graph management and upon finding it, Atlas skips rest of the
initialization (creation of indexes like vertex_index, edge_index,
fulltext_index). This results in subsequent queries to fail with error
"vertex_index" not found.
The fix is to defer loading of bootstrap types to instance-activation. Also,
added info level logs to trace type initialization and index creation
activities.

Testing
-------
Verified that Atlas starts up successfully in the following cases:
- Single instance, with an empty store (i.e. first time)
- Single instance, with non-empty store
- HA: multiple instances, with an empty store
- HA: multiple instances, with non-empty store
Thanks,
