Remove a lib thrift jar from the distribution

[Nirothipan]

Description: Currently the distribution has two lib thrift jars. We need to remove one. Also when there is class not found exception happening when the lib thrift version is defined in parent pom. Hence it is hard coded here https://github.com/wso2/micro-integrator/blob/master/integration/tests-common/integration-test-utils/pom.xml#L20 . We need to remove this as well.
