bolkedebruin 8f07a39af7 Skip OS cache on Linux when pulling segments (#5421)
Druid relies on the page cache of Linux in order to have memory segments.
However when loading segments from deep storage or rebalancing the page
cache can get poisoned by segments that should not be in memory yet.
This can significantly slow down Druid in case rebalancing happens
as data that might not be queried often is suddenly in the page cache.

This PR implements the same logic as is in Apache Cassandra and Apache
Bookkeeper.

Closes #4746
