Querying `getRoleListOfUser(userName)` for each application for the same user

[kasunsiyambalapitiya]

Description:
When loading the Service Provider page for the logged in user from Management console, the following method isUserAuthorized is executed for each application which in turn queries the UserStore with the following method getRoleListOfUser(username) of the relevant userstore for getting roles list of the logged in user in order to match with the applicationRoleName. Here the above call is redundant as it will always return the same role list of the logged in user for each application.

The above flow can be optimized such that userStoreManager.getRoleListOfUser(username); is called to get roles list of the logged in user first and then validate the above-obtained roles with each applicationRoleName
