[NO ISSUE][TXN] Remove Synchronization on TransactionContext

- user model changes: no

- storage format changes: no

- interface changes: no

Details:

- Currently the flag indicating if a transaction timed out

synchronizes on the transaction context which makes it

a hot spot when multiple threads on the same transactions

attempting to access that flag. This change removes that

synchronization and replaces it with a volatile variable.

Details:

- Do not delete corrupted checkpoint files until a valid

checkpoint is persisted. This ensure a forged checkpoint

that will force recovery to start from the begining is

- Attempt to read the latest checkpoint file right after

writing it and before attempting cleaning up invalid and

old checkpoint files.

- Use on disk files to determine next checkpoint id to

account for existing corrupted checkpoints.

- Maintain two older checkpoint files in addition to the

latest one.

- Catch all exceptions on checkpointing failures since it is

a try operation.

- Add test scenairo for the new checkpoints clean up behavior.

- Before synchronizing replicas, stop datasets checkpointing to

prevent new files from being generated due to async IO operations

triggered by checkpointing.

- Instead of sync'ing current files to replicas then scheduling a flush

and sync'ing any newly generated files, just flush datasets before

the initial sync then sync all the files in one go.

[NO ISSUE][REPL] Ensure Valid Component ID is Initialized On Replica Sync

- user model changes: no

- storage format changes: no

- interface changes: yes

Details:

- Currently, the first time a replica is synchronized from master,

the valid component id on each replicated index's initial checkpoint

will be the initial value of a component id (-1). This value is

fixed when the the replica receives a flushed component from

the index. However, if the master fails before any component is

flushed to a replica and that replica is promoted to master, it

will start from an invalid component id. This change ensures that

the initial checkpoint of replicated indexes is initialized to

the maximum component id that appears on master. This will ensure

that if the replica is promoted, it will at least start from

a component that wasn't previously used on master.

- Replace assertion of component ids validation by illegal state.

- user model changes: no

- storage format changes: yes

- interface changes: yes

Details:

- Replace the usage of system clock timestamps in LSM

index components file names by a sequencer. The next

sequence id to use is determined by checking the list

of existing components on disk. Note that due to a

rollback, an index checkpoint file may have last valid

component sequence which is greater than what is on disk.

This should not cause any issues since only components

that have a sequence greater than that appears in the

checkpoint will be deleted.

- Replace the usage of system clock timestamps in LSM

index components ids by a monotonically increasing

sequencer. The sequencer is initialized after restarts

by the last valid component id that appears in the

index checkpoint.

- Refactor the logic to generate flush/merge file names.

- Refactor the logic to check invalid components.

- Adapt test cases to new naming format.

change the config stored in MetadataProvider from <String,String>
