Recognise read sqlQueries passed in statement.execute(***) to run them on REPLICA

[afaruga-atlassian]

Methods like ReplicaStatement.execute(String, *** ) (listed below), are run on MAIN, as they're treated as write operations.
They can be used by application to either pass WRITE or READ SQL query.
Currently, all execute()*** invocations are treated as write operations.
For applications that use execute()for READ operations this won't move those queries to REPLICA.

Example methods:

• connection.prepareStatement(SIMPLE_QUERY).execute();
• connection.prepareStatement(SIMPLE_QUERY).execute(SIMPLE_QUERY);
• connection.prepareStatement(SIMPLE_QUERY).execute(SIMPLE_QUERY, Statement.RETURN_GENERATED_KEYS);
• connection.prepareStatement(SIMPLE_QUERY).execute(SIMPLE_QUERY, new String[]{"test"});
• connection.prepareStatement(SIMPLE_QUERY).execute(SIMPLE_QUERY, new int[]{123});
• connection.prepareStatement(SIMPLE_QUERY, new int[]{123}).execute(SIMPLE_QUERY, new int[]{123});
