[BUG]: Setting max_lifetime and max_timeout to None for in-memory DB (#4347)

#4332

## Description of changes

*Summarize the changes made by this PR.*
 - Improvements & Bug fixes
- Default sqlx pool options close idle connections for in-memory DB
after 10mins which clears the data in the DB causing subsequent client
calls to fail with sqlite errors. This PR sets max_lifetime and
idle_timeout for in-memmory DB to None which prevents connection from
being reaped

## Test plan
*How are these changes tested?*

- [ ] Tests pass locally with `pytest` for python, `yarn test` for js,
`cargo test` for rust
