This feature will provide role based access to each individual component of PEM. Until PEM 7.1, if any user is member of 'pem_user' then they can view the dashboard and access some read only features of PEM, but can't access features like Alerts, Probe, Capacity Manager, Tuning Wizard, etc. With this new feature, we have added new roles for each individual component of PEM. To access any PEM component, the user should be a member of the respective role.
