[#3220] Implement one way bitmap
220b454 
Summary:
During transaction sealing implementation we store set of replicated batches in running transaction.
This diff adds bitmap that is optimized for this particular scenario:
  1) Bits could only be set, i.e. clear is not allowed.
  2) Usually bits are getting set in increasing order.
  3) Bitmap is frequently encoded and skipped, but rarely decoded.

Test Plan: ybd debug --cxx-test bitmap-test --gtest_filter *.OneWayBitmap*

[#3220] Extract CleanupTransaction from YBTransaction
1166e5a 
Summary:
When sealed transaction is applied, coordinator cleans up its intents.
We already have such functionality in YBTransaction, i.e. client part of transaction.

So extracted it to separate utility function.

Test Plan: Jenkins

[#3220] Track replicated batches at transaction participant
0f0aa07 
Summary:
To implement the "transaction sealing" protocol, we should track
transactional batches replicated at each transaction participant.  So
with this diff, YBTransaction now tracks all batches sent to participant
tablets as part of the transaction, and assigns an index to each batch.
When a transactional batch is replicated, we add its index to the set of
indexes of replicated batches for the transaction at the transaction
participant.

Test Plan: ybd debug --gtest_filter SealTxnTest.NumBatches*

[#3220] Implement transaction sealing w/o abort
d0c2f48 
Summary:
This diff implements transaction sealing w/o the ability to abort sealed transactions and intents apply.
(It will be addressed by upcoming diffs).

Added ability to request transaction status at the participant, i.e. number of replicated batches, etc.

Test Plan: ybd debug --cxx-test seal-txn-test
