[trmartin4]

Type of change

- [ ] Bug fix
- [ ] New feature development
- [X] Tech debt (refactoring, code cleanup, dependency upgrades, etc)
- [ ] Build/deploy pipeline (DevOps)
- [ ] Other

Objective

We are currently making ~70k calls/minute to the /config endpoint. This compares to around ~6k/minute for sync, for comparison. In testing, I've identified some ways to reduce these calls incrementally.

• There appeared to be a duplicate nexting of the activeAccount$ observable on account change. The setActiveAccount and addAccount were both issuing the change.
• I added distinctUntilChanged to the subscription on the EnvironmentService, so that if the activeAccount$ were to next the same user ID it will not re-retrieve the environment URLs. The assumption here is that a given user will have the same environment URLs when changing accounts.

Code changes

• environment.service.ts: Added distinctUntilChanged
• state.service.ts: Removed extra observable next on account change

Before you submit

• Please add unit tests where it makes sense to do so (encouraged but not required)
• If this change requires a documentation update - notify the documentation team
• If this change has particular deployment requirements - notify the DevOps team
• Ensure that all UI additions follow WCAG AA requirements
