  - [vyos_vrouter] Support https endpoints
    
    JIRA: FUNCTEST-881
    
    vyos_vrouter did not support https endpoints [1].
    
    I fixed the following two points.
     1. Modifying blueprint of Cloudify.
     2. Changing nova client of utilvnf module.
    
    Point 1
     I added command of support https endpoint to blueprint of vyos_vrouter.
     The Blueprint of vyos_vrouter is on our github repository [2].
     I updated our repository.
    
    Point 2
     I changed nova client of utilvnf module.
     Utilvnf module is utility module of vyos_vrouter.
     Nova client of utilvnf module did not support https endpoints.
     So, I changed to use nova client of snaps.
    
    After fixed the source code, I confirmed the vyos_vrouter was succeeded in the following two environments.
     1. Our labs   (Instoller:fuel,    environment of https endpoints)
     2. Orange POD (Instoller:compass, environment of http endpoints)
