[Human App] fix: cache-manager ttl usage

[dnechay]

Description

Fixing invalid usage of cache-manager ttl value.

Summary of changes

We use @nestjs/[email protected] that under the hood just creates instance of cache-manager package (ref) that is being installed in the project (5.4.0 in our case). When we import Cache type for it - we see that ttl is just a third argument and is in milliseconds. Under the hood cache-manager calls the set method of the store (ref) in the same fashion. However, when we register cache module, we create a redis store based on cache-manager-redis-store, that accepts ttl in options argument (ref), so it's not compatible with the used version of cache-manager, so in order to fix that we have two options:

• downgrade cache-manager to v4, that used same signature (ref)
• use different store, e.g. cache-manager-redis-yet that is compatible with v5 (ref)

I decided to go with the second option due to next reasons:

• using this store is mentioned in nestjs docs, so it's not surprising
• downgrading to v4 might introduce some bugs/regressions
• even though cache-manager-redis-yet is deprecated, it can be removed from npm due to dependencies and number of downloads; and at the same time nestjs/cache-manager should introduce support for the cache-manager/v6 soone that should eliminate such dep (ref); once it's there - we will upgrade and also get back to using seconds

Also refactored healthcheck for cache-manager: under the hood it can be any storage (Redis, Memcached, Mongo, etc.) and in case if health indicator depends on store's API we can miss updating our healthcheck if we change the store

How test the changes

• simply run the app and use TTL command to check that values are set on all necessary keys
• existing unit tests pass
