I attempted to refactor so that the caller of `wrap_method` passes in a
block, rather than a method name, but I was unsuccessful.

I kept getting the following error:

NoMethodError:
        undefined method `cache_method_output' for Repository:Class

If you can figure this out, then feel free to dry up these class methods
again without doing a send-within-a-send.

* Only truthy values are cached in Redis.
* All values are cached in RequestStore and in an instance variable.

And reuse `Gitlab::Utils::StrongMemoize`.

There is a subtle behavior change required to reuse StrongMemoize in
this case. The early fallback check now occurs *before* reading the
memoized value instead of after.

I think this is fine since a memoized value should only exist if
`exists?` is also already memoized as `true`.

Fast lookup of authorized SSH keys in the database was ported to CE in

rake task and assumes yes if the force env variable is set.

Backport of js and vue files from closing epics

* Fix typo in context 'when request store is active'
* Rearrange test since the instance variable always gets set now,
even if RequestStore is active

Even if it doesn’t save lines of code, since people will tend to use
code they’ve seen. And `SafeRequestStore` is safer since you
don’t have to remember to check `RequestStore.active?`.

These are clear wins.

Makes it easier and safer to use RequestStore because you don't need to
check `RequestStore.active?` before using it. You just have to use
`Gitlab::SafeRequestStore` instead.
