DB Connection Pool Create based on notification

Issue

• We have a requirement to Refresh/Create New connection pool created by Fuse service based on notification received on queue.
• We are creating DB related beans at startup of service using below configuration

<bean class="org.apache.commons.dbcp2.BasicDataSource" id="dataSourceMAIN"
                name="dataSourceMAIN" primary="true">
                <property name="driverClassName" value="${dataSourceMAIN.MAIN.driverClassName}" />
