feat(sifrr-seo): Individual cache expire logic about sifrr

[aadityataparia]

• Refresh cache function, (useful in persisted cache storage).

There are a few ways to update cache after fetching response,

• Include response hash/e-tag/last modified in cache key or updating if that changes

[aadityataparia]

Best Plan: Store cacheKey based on response and update cache if it changes in normal requests.

But this will need complex logic and testing.

Save expire time with cache, if current time is more than expiring time then re render.
