Hazel KimandGitHub c6bebde733 enabled shadow read for secondary visibility store (#5976)
## What changed?
<!-- Describe what has changed in this PR -->
- added EnableShadowReadMode config (default to false)
- if shadow read mode is enabled, perform shadow read from the secondary
visibility store for visibility read requests

## Why?
<!-- Tell your future self why have you made these changes -->
- to measure latency metrics from both visibility stores

## How did you test it?
<!-- How have you verified this change? Tested locally? Added a unit
test? Checked in staging env? -->
- tested locally, and verified that visibility read requests from both
visibility stores are getting reasonably same latencies

## Potential risks
<!-- Assuming the worst case, what can be broken when deploying this
change to production? -->

## Documentation
<!-- Have you made sure this change doesn't falsify anything currently
stated in `docs/`? If significant
new behavior is added, have you described that in `docs/`? -->

## Is hotfix candidate?
<!-- Is this PR a hotfix candidate or does it require a notification to
be sent to the broader community? (Yes/No) -->
