Jim Gauld acefd544f0 Mitigate memory leak of sessions by disabling sudo for sriov agent 
The sriov agent was polling devices via 'sudo ip link show',
and this resulted in a severe memory leak. The usage of 'sudo'
uses the host 'dbus-daemon', and somewhere the host does not
clean up login sessions.

Symptoms:
- gradual run out of memory until system unstable, host spontaneous
  reboot due to delay or OOM
- huge growth of kernel slab
- thousands of /sys/fs/cgroup/systemd/user.slice/user-0.slice
  session-x*.scope files with empty 'tasks', i.e., sessions
  that should have deleted
- huge latency seen with ssh and various systemd commands

The problem is mitigated by disabling 'sudo' for sriov agent, using
a helm override that configures [agent]/root_helper='' .

Testing:
- Verified that we could launch a VM with SR-IOV interface;
  VFs were able to set MAC and VLAN attributes.

Closes-Bug: 1815106
