d8bd9fc7b3 Range Locking: Allow different LockManagers, add Range Lock definitions (#7443)
Summary:
This PR has two commits:
1.  Modify the code to allow different Lock Managers (of any kind) to be used.  It is implied that a LockManager uses its own custom LockTracker.
2.  Add definitions for Range Locking (class Endpoint and GetRangeLock() function.

cheng-chang, is this what you've had in mind (should the PR have both item 1 and item 2?)

0ea7db768e Abstract out LockManager interface (#7532)
Summary:
In order to be able to introduce more locking protocols, we need to abstract out the locking subsystem in TransactionDB into a set of interfaces.

PR https://github.com/facebook/rocksdb/pull/7013 introduces interface `LockTracker`. This PR is a follow up to take the first step to abstract out a `LockManager` interface.

Further modifications to the interface may be needed when introducing the first implementation of range lock. But the idea here is to put the range lock implementation based on range tree under the `utilities/transactions/lock/range/range_tree`.
