Improve cache creation

Follows #145 (comment)

ATM, we create a new cache struct each time we need it. We could simplify that by having a singleton or having it stored in the API context.

Todo

• Decide how to store the cache struct
• Implement the changes
• Ensure cache is still working properly

It's a technical issue, would make the code a tiny bit cleaner and improve a very little performances

Not a priority IMO
