Rohit Yadav b2b496288d CLOUDSTACK-8034: Hash user IDs for SAML authentication
The User table's UUID column is restricted to 40 chars only, since we don't
know how long the nameID/userID of a SAML authenticated user will be - the fix
hashes that user ID and takes a substring of length 40 chars. For hashing,
SHA256 is used which returns a 64 char length string.

- Fix tests, add test cases
- Improve checkSAMLUser method
- Use SHA256 one way hashing to create unique UUID for SAML users
