Sync with upstream

[agodnic]

Summary

Sync with the latest upstream commit. In particular, add support for the online-only parameter in GET /v2/accounts to search for online accounts.

Note that the parameter is disabled by default.

Performance

The performance of is-online=true lookups can be improved with the following index:
