Subject: [PATCH] Add search cache workflow (#5560)

Added separate workflow that search cache, it will allow us to remove
duplication of this logic in `main.yml`, `full.yml` and `schedule.yml`

! This solution won't work if PR changes search-cache.yml, but this
workflow is supposed to almost never change
