Adding a datasource poolname to prevent AccessControlException

* Fix for #4 java.security.AccessControlException

48 - passing the parameter of the connPoolKey to the function createHikariDataSource
74 - extending the definition of the function createHikariDataSource with an integer parameter
76 - inserted the setting of the poolName of the dataSource to prevent the generation of the poolnumber globally.

* Update JdbcConnectionManager.java

* Added name for connection pool
