Servers hang for one minute during startup #2699

Description:
In the server startup we observed an excessive usage of getConnectionId() method [1] and in other publisher/store functions. With our current implementation of the method, connectionId has been constructed as follows.

connectionId = (connectionMetaData.getUserName() != null ? connectionMetaData.getUserName().split("@")[0] : connectionMetaData.getUserName()) + "@" + connectionMetaData.getURL();

connectionMetaData.getUserName() is executing internal DB queries to get the User name from the database continuously, which causes the performance impact with some of the environment conditions (eg: slow network). As we analyzed this has caused the slowness in the server startup and other functionalities in all the environments.
