Subject: [PATCH 1/2] :sparkles: Adds cache to returned op items

To cache op list-items results I must first create a file everytime I get any
return from the command itself.

On this commit, I am creating the logic to save the return from op list-items
into a given file for further usage.

Now, I just need to add the logic to fetch from this file instead, if the file
is new enought.

Subject: [PATCH 2/2] :sparkles: Uses cache_file if available

Now that I can cache the op list-items result, I need to use the cache instead
of getting it online, if it exists. It is important to have a TTL on the cache
file too.

On this commit I'm going to add the logic to use the cache file (if applicable)
and also create a rule to use it only when the cache is recent.

Now, I've finished the feature and can start using it.
