SCIM.java

/*Existing Implementation of REST Endpoints:

UserEndpoint

//Create an user
Reads JSON representation of user from a file SCIMUser.json, parses it into 
SCIMUser object(includes lot of details about scimuser) and
populates PL IDM User object with basic information(id, loginName, firstName, lastName)
with the help of SCIMUser and stores user it in identityManager. Sends back String representation
of SCIMUser as JSON.

//Retrieve a User
Retrieves PL IDM User from identityManager of the desired id via IdentityQuery. 
Populates the basic info (id, loginName, firstName,
lastName) of PL IDM User into newly created SCIMUser object
(SCIMUser object lacks other required information).
Sends back String representation of SCIMUser as JSON.

SCIMUser is mapped to IDM User for storage. Since, IDM User is able to store only basic info about SCIMUser,
we aren't able to retrieve all the details about SCIMUser while retrieving it from identityManager.

Current Implementation/Idea:

SCIMUser will be changed to SCIMUserType which will extend AbstractIdentityType.
SCIMUserType will act as identity model for storage in identityManager. 
SCIMUserType will be same as CertificateType model in PKI*/
