In some environments it is not allowed to create a schema
by the application itself. With this change the AbstractJDBCDriver
now tests if an existing table is empty and executes further
statements in the same way as if the table does not exist.
Replace GenericSQLProvider and other implementation by a single
PropertySQLProvider that uses properties to define SQL queries.
SQL queries are loaded from the journal-sql.properties file.
Queries specific to a DB dialect can be specified by adding a suffix to
the key of the generic property.
For example, the generic property to create a file Table is:
create-file-table = CREATE TABLE %s (ID BIGINT AUTO_INCREMENT, ...)
This property can be customized for Derby by using the
create-file-table.derby property:
create-file-table.derby=CREATE TABLE %s (ID BIGINT NOT NULL GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1),...

In order to make the JDBC Node Manager more resilient has been implemented:
- recovering with fixed number of retries during the NodeId setup + unrecoverable failure otherwise
- unrecoverable fail on exceptions while renewing a lease lock
In addition, in different parts of these critical processes are added more log informations to help diagnose.
The JDBCSequentialFile blocks on the writeLock when opening. There is
no need to block here, in fact it may cause issues when opening and
syncing concurrently. Instead an AtomicBoolean is enough to prevent the
file from being reloaded.
Multiplication operations where the operands have type `int` but the
result is cast to `long` may lead to overflow.
Fixes two instances of this problem, by ensuring the operands are cast
to `long` during multiplication.
This resolves the "Result of integer multiplication cast to long"

with this we could send and receive message in their raw format,
without requiring conversions to Core.
- MessageImpl and ServerMessage are removed as part of this
- AMQPMessage and CoreMessage will have the specialized message format for each protocol
- The protocol manager is now responsible to send the message
- The message will provide an encoder for journal and paging
