[NO ISSUE][TX] Introduce Atomic Transactions

- user model changes: no
- storage format changes: no
- interface changes: yes
  - Redesign and simplify ITransactionManager API
  - Redesign and simplify ITransactionContext API

Details:
- Introduce atomic transactions. Unlike entity level transaction,
  atomic transaction do not generate any entity commit logs and
  may modify multiple primary indexes. Therefore, either all the
  operations of an atomic transaction will be committed or nothing.
  Atomic transactions  are used by metadata transactions, while other
  transactions still use entity level transactions.
- Add index resource id to AbstractOperationCallback.
- Refactor metadata index modification code.
- Remove unused class MutableResourceId
- Remove unused class FieldsHashValueGenerator
- Add test case for concurrent metadata transactions.
