[4.x] Support database cache store tenancy (#1290) (resolve #852)

* Initial implementation (lukinovec)

* Make sure DatabaseCacheBootstrapper runs after DatabaseTenancyBootstrapper, misc wip changes

* Fix withTenantDatabases()

* Add failing test (GlobalCacheTest)

* Configure globalCache's DB stores to use central connection instead of default connection every time it's reinstantiated

* Make GlobalCache facade not cached. Even though it wasn't causing issues
in our existing tests, it likely was flaky, and making it not $cached
makes it now consistent with global_cache() - always getting a new
CacheManager from the globalCache container binding

* Add database connection assertions in GlobalCacheTest

* Run all cached resolver/global cache tests with DatabaseCacheBootstrapper

* Reset adjustCacheManagerUsing in revert() and TestCase

* Reset static $stores property

* Finalize GlobalCache-related changes

* tests: remove pointless cache TTLs

* Refactor DatabaseCacheBootstrapper

* Refactor tests
