Summary:
Right now the way we do BlockIter::Prev() is like this
- Go to the beginning of the restart interval
- Keep moving forward (and decoding keys using ParseNextKey()) until we reach the desired key
This can be optimized by caching the decoded entries in the first pass and reusing them in consecutive BlockIter::Prev() calls
Before caching

Summary:
Two changes here:
- Remove dead Jenkins related code which is no longer relevant.
- Support `arc diff --preview`. Currently it doesn't work because a step which applies a diff assumes that a revision has been created. Which in case of `--preview` isn't. Therefore diff can't be applied and validation fails. Solution is to use `--nocommit` because for validation purposes performing a commit isn't necessary.
Test Plan:
- Current changes are submitted using `arc diff --preview`.
- All the pre-commit verification tests passed.

Summary:
Add option to not flush memtable on open()
In case the option is enabled, don't delete existing log files by not updating log numbers to MANIFEST.
Will still flush if we need to (e.g. memtable full in the middle). In that case we also flush final memtable.
If wal_recovery_mode = kPointInTimeRecovery, do not halt immediately after encounter corruption. Instead, check if seq id of next log file is last_log_sequence + 1. In that case we continue recovery.

Summary:
This provides provides an implementation of PersistentCacheTier that is
specialized for RAM. This tier does not persist data though.
Why do we need this tier ?
This is ideal as tier 0. This tier can host data that is too hot.
Why can't we use Cache variants ?
Yes you can use them instead. This tier can potentially outperform BlockCache
in RAW mode by virtue of compression and compressed cache in block cache doesn't
seem very popular. Potentially this tier can be modified to under stand the
disadvantage of the tier below and retain data that the tier below is bad at
handling (for example index and bloom data that is huge in size)
