Memory Store Option

[mehmetaydogduu]

I think per request cache is good but process level caching may be an alternative an more faster option.

The current implementation uses ActiveSupport::CurrentAttributes

Another adapter can be implemented with ActiveSupport::Cache::MemoryStore API.

memory_store = ActiveSupport::Cache::MemoryStore.new(size: 64.megabytes)
memory_store.write('serialized_settings', Settings.all.to_json)
memory_store.read('serialized_settings')
memory_store.delete('serialized_settings')

This idea is open to comments here.
