[PS-93] Distributed Ip rate limiting (#2060)

* Upgrade AspNetCoreRateLimiter and enable redis distributed cache for rate limiting.

- Upgrades AspNetCoreRateLimiter to 4.0.2, which required updating NewtonSoft.Json to 13.0.1.
- Replaces Microsoft.Extensions.Caching.Redis with Microsoft.Extensions.Caching.StackExchangeRedis as the original was deprecated and conflicted with the latest AspNetCoreRateLimiter
- Adds startup task to Program.cs for Api/Identity projects to support AspNetCoreRateLimiters breaking changes for seeding its stores.
- Adds a Redis connection string option to GlobalSettings

* Cleanup Redis distributed cache registration

- Add new AddDistributedCache service collection extension to add either a Memory or Redis distributed cache.
- Remove distributed cache registration from Identity service collection extension.
- Add IpRateLimitSeedStartupService.cs to run at application startup to seed the Ip rate limiting policies.
