Move role-specific parameters of DPDK to roles file from the environment file

[Saravanan KR]

Providing role specific parameters using the environment files, has to be manually added to specific role in user's environment file, for example,

parameter_defaults:
  ComputeOvsDpdkParameters:
    VhostuserSocketGroup: "hugetlbfs"

Above environment works for ComputeOvsDpdk role but if there multiple OVS-DPDK roles like ComputeOvsDpdkDell and ComputeOvsDpdkHp, this environment file cannot be used. Instead of using environment file, if the same parameter is added to the RoleParamtersDefault of roles/ComputeOvsDpdk.yaml file, then users will copy the roles data file with the whole content so that it will be retained for all the roles.

    Make VhostuserSocketGroup param as mandatory for ComputeOvsDpdkRT role

    Without VhostuserSocketGroup configured as hugetlbfs (required by
    nova-libvirt and neutron-ovs-dpdk-agent services), guest VMs
    could not be created. Add this parameter to the roles data file.
