Create a new test called FUNCintentRest

The intent rest API covers host and point intents, The FUNintent test suite uses ONOS CLI as its main interface. The FUNCintent also test multi-to-single and single-to-multi point intent which the REST api does not support. The FUNCintentRest should test the same procedures as the ONOS CLI testing with some minor changes on the topo file. The wrapper function use in the FUNCintent also uses summary function in the test, and should be changed in the FUNCintentRest api. Only minor changes are needed to turn FUNCintent to FUNCintentRest.
