perf(query): reduce user query duration (#10037)

# Which Problems Are Solved

The resource usage to query user(s) on the database was high and
therefore could have performance impact.

# How the Problems Are Solved

Database queries involving the users and loginnames table were improved
and an index was added for user by email query.

# Additional Changes

- spellchecks
- updated apis on load tests

# additional info

needs cherry pick to v3
