quorum calculation getLatestFileInfo should be itself (#13717)

Browse Source 
FileInfo quorum shouldn't be passed down, instead
inferred after obtaining a maximally occurring FileInfo.

This PR also changes other functions that rely on
wrong quorum calculation.

Update tests as well to handle the proper requirement. All
these changes are needed when migrating from older deployments
where we used to set N/2 quorum for reads to EC:4 parity in
newer releases.
