SingleStore JDBC Driver 1.2.0

General updates:

• Refactoring/java docs
• Allow empty username for JWT authentication
• new connection string parameters:
  transformedBitIsBoolean: Indicate for TINYINT in column metadata that type is BOOLEAN in place of BIT. A value of 0 is considered FALSE, non-zero values are considered TRUE. Default is false.
  transactionReplay: When having a failover, can current transaction beeing re-executed, having a completly transparent failover. All commands must be idempotent. Default false.
  transactionReplaySize: replay cache buffer maximum size. If a transaction has more command that this size and a failover occurs, transaction will then not be replayed, just throwing an exception error. (Integer) default 64.
  maxAllowedPacket: permit to driver to avoid sending command with size > to server max_allowed_packet, throwing an error in place of server dropping the connection.

Metadata updates:

• added UNSIGNED type name
• BOOLEAN type for tinyInt1isBit & transformedBitIsBoolean configs and BIT for tinyInt1isBit
