Added status for roles and option to delete roles and enable/disable roles

@vishwasbabu 

1. Added Sql Script : V230__role_status_and_correspoding_permissions.
2. Added new features : disable or enable and delete Role
For enable or disable : values id DB m_role 0 or 1
For delete : Hard delete row from table 
3. If role associated with any one user we can not delete or disable the role
can remove By RoleId from this method (makes method name shorter). Howver, this is just a suggestion, feel free to ignore the same
