When we switched from a single-threaded application server (Unicorn) to
a multithreaded one (Puma), we did not realize that Puma often reaps
threads after a request is done and recreates them later. This makes the
thread-local cache ineffective, as the cache does not store anything
beyond the lifetime of the thread.

Since `ActiveSupport::Cache::MemoryStore` is thread-safe, we should be
able to switch the L1 cache for the feature flag list to use this to
reduce load on Redis.

Since read and write access is synchronized, this does have the side
effect of adding contention when feature flags are accessed.

We made a similar change in
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/26935, and this
seems to be working fine.

should create a follow-up issue _after_ the check got the majority.
