Support for intel txt. Made fixes for the following:
1. Fixed the apidocs build.
2. While checking for Saml assertion to check if a host is trusted or not, verifyTrustAssertion api was marking the assertion as invalid. Fixed this by using the getTrustForMultipleHosts api which doesn't check for saml assertions.
3. If two connections are opened to the attestation server with the same user credentials and they independently try to check the trust assertions of the host; the api fails with unauthorized exception error. Fixed it by synchronizing it by locking the attestation server row entry in the db.
