SearchQueryBuilder: Replace SmartSearchBar in metrics page

[malwilley]

Background

<SearchQueryBuilder /> is meant to be the next generation of <SmartSearchBar /> and should ideally be replaced in all app surfaces. At this time, it is only implemented on issues pages. Because different parts of the app use this search bar differently, we need to implement and test it thoroughly ensure that is works for all use cases.

Requirements

• Under a feature flag for this product area (already created), render SearchQueryBuilder instead of SmartSearchBar
• If your search bar has a large number of filter keys, implement the filterKeySections prop to display them in an organized fashion. How your filter keys get categorized is up to you!
• If you come across any missing feature that are critical to your use case, please note them and bring this up to the issues team.

Resources

• See here for SearchQueryBuilder documentation which should help you understand how to use the component and how SmartSearchBar props map to the new ones.
• A list of feature flags has been generated for each product surface. See here for the full list. These flags are already enabled for internal orgs.
